RK3588 Custom M.2 Expansion Board, WF-C3588-I1, AndroidSBC, Toulouse

TL;DR: RK3588 Custom M.2 Expansion Board

Toulouse, France - September 12, 2026. Buyers in Toulouse took the 297th WF-C3588-I1 consignment from the Wanlin Longgang plant this week, 26,605 units in total, with the destination file prepared for France customs.

AndroidSBC regulatory bulletin on CE, FCC, UKCA, RoHS and IEC 62368-1 coverage for the WF-C3588 serving Toulouse, France. The line spans custom Android motherboards at the entry variant through core-board-plus-carrier work at the SOM end, all on the same Rockchip RK3588 silicon with 6 TOPS NPU, 8K H.265 decode and up to 32GB of LPDDR5. AndroidSBC ships the full range from the Wanlin Longgang plant, and Toulouse buyers can mix custom variants inside a single framework agreement rather than opening a new supplier file for each product line.

About AndroidSBC and the Rockchip RK3588 Board Family

AndroidSBC is the export brand of Wanlin Manufacturing Group, a Shenzhen source-factory group that has spent more than a decade building custom OEM and ODM boards on Rockchip silicon. The line this release covers is the WF-C3588: nine custom motherboard variants built on the same Rockchip RK3588 octa-core 8nm platform with 6 TOPS NPU and 8K H.265 video, covering custom Android motherboards, custom industrial boards, core board and SOM carrier design, custom signage and video wall boards, custom kiosk and POS boards, custom robotics controllers, custom NVR boards, custom edge AI boards, and custom ARM PC and NAS boards. Wanlin's Longgang plant in Shenzhen builds the WF-C3588 for France OEM, integrator and distributor programmes. For a Toulouse buyer the practical value of the line is that one silicon and one supplier file cover nine custom categories.

WF-C3588-I1 Technical Specifications

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-C3588-I1 (Custom Industrial Motherboard for Fanless and Wide-Temperature Control) holds its display output and its decoder load at the same time through the burn-in loop, a combination that the legacy boards in the comparison column cannot sustain. For France importers sourcing the WF-Series, the 8GB + 32GB (WF-C3588-I1-B) variant is the typical configuration for the custom industrial control and HMI programmes use case, with a sustained weekly capacity of 5,000 pcs/wk on the Longgang line.

Challenges in Sourcing Custom Industrial Motherboard for Fanless and Wide-Temperature Control for France Buyers

The custom industrial motherboard for fanless and wide-temperature control sourcing question that Toulouse distributors keep coming back to is continuity across quarters. The Rockchip RK3588 requires a dedicated wafer slot, and a 26,605-unit order placed against broker inventory often turns into a two-month slip with no warning. Then comes the software layer. A board that boots is not a board that holds a certified stack under a 72-hour loop, and France buyers typically find the difference in their own warehouse rather than at the factory.

The third exposure is paperwork. Factories that stamp marks without holding the underlying test reports leave the importer to produce a Technical File after the fact, which is exactly when the container is sitting in a bonded yard. AndroidSBC runs the custom board build, the certified image burn, the burn-in record and the certification file inside the Longgang plant, so the lot arrives complete rather than in pieces. The nine variants in the WF-C3588 cover industrial HMIs, panel PCs, PLC upgrades, SCADA nodes, DIN-rail controllers, factory automation, data acquisition, IIoT gateways, and machine control and each one carries three memory configurations, which keeps Toulouse and France buyers on standard custom SKUs for most requirements.

Compliance for France is handled at the factory rather than after arrival. In France ANFR radio registration is separate from the CE marking, and buyers normally ask for both before releasing a purchase order. The Longgang export desk builds the destination-market file for CE marking with ANFR radio interface registration administered by ANFR and issues it alongside the standard multi-market pack (CE, FCC, UKCA, RoHS, REACH), with the shipment booked into Port of Le Havre on the Le Havre to Yantian lane.

Competitive Comparison: WF-C3588-I1 vs Competing RK3588 Boards

The comparison set for the custom industrial motherboard for fanless and wide-temperature control socket splits three ways: catalogue boards priced low with fixed everything, re-badged boards that cannot answer a schematic question, and custom platforms that take the I/O, memory and firmware changes in stride. The WF-C3588-I1 sits in the third group, differentiated by Rockchip RK3588, by customization depth, and by the factory-side certified image burn.

• vs commercial boards in industrial dress: the WF-C3588-I1 is designed to -40C to 85C from the schematic up, not a consumer board with a bigger heatsink.
• vs local integrator bundles: the carrier design, the BSP port and the DIN-rail chassis all come from one Longgang engineering desk, so responsibility never splits across vendors.
• vs legacy PLC upgrade paths: the 6 TOPS NPU adds on-device vision and predictive maintenance to a PLC retrofit without a separate AI box.
• vs trading-company boards: the per-lot Technical File, the aging record and the EMC pre-compliance bench all live inside the source factory.

Global Custom Industrial Motherboard and Panel PC Market Trends

Order timing in Toulouse now tracks the Custom Industrial Motherboard and Panel PC curve rather than the calendar-year budget. MarketsandMarkets sizes the Edge AI hardware segment at USD 26.9 billion for 2025 with a 32.7 percent CAGR through 2030 (MarketsandMarkets, 2025-2030), the silicon baseline that France buyers keep on the desk when they negotiate custom board allocation. Three patterns are visible in the WF-C3588 book:

• Industrial HMI panel: a machine builder replaces an aging Windows panel with a fanless HMI running a Yocto image and a custom UI.
• Display and signage refresh cycles: a longer content loop and a higher panel resolution now define the refresh trigger. The WF-C3588-I1 board carries that headroom without a board change.
• SCADA edge node: a utility deploys DIN-rail controllers that aggregate substation data and push it over dual Gigabit links.

What the Custom Industrial Motherboard and Panel PC data does not show is the operational cost of a supply break, which is why Toulouse buyers increasingly weight supplier continuity above a marginal price difference.

Taken together, the three patterns explain why France buyers are moving from single orders to twelve-month framework agreements with a monthly lot cadence, especially on custom board programmes that cannot absorb a supply gap.

Partner Success Story: Ostra Vision Labs in Toulouse, France

Ostra Vision Labs, a machine vision integrator serving the France market, deployed 4,900 custom WF-C3588-E7 edge AI boards for factory inspection lines. The rollout covered the industrial hmi panel, scada edge node, and factory automation cell workloads, with AndroidSBC handling the burn-in, the certification scope, and the palletisation at the Wanlin Longgang plant.

• Deployed: 4,900 custom WF-C3588-E7 edge AI boards for factory inspection lines
• Region: Toulouse, France
• Models used: WF-C3588-I1 (lead SKU), plus eight sibling custom RK3588 board variants in the same platform family
• Certifications handled: CE, FCC, UKCA, RoHS, REACH, IEC 62368-1, EN 55032, EN 55035, plus optional UL 60950-1, GMS, Widevine L1 and Dolby Audio per variant
• Logistics: FOB Nansha with the Wanlin Group Longgang source factory named on the export declaration, entering Port of Le Havre via the Le Havre to Yantian lane

"Our defect model went from ONNX to RKNN inside a week with their engineering desk, not a forum thread. The boards run four cameras per cell with classification at line speed, and the per-unit barcode makes every RMA a root-cause report instead of a swap."

- Daniel Reyes, VP Product

Field Report: the AndroidSBC booth at an international broadcast and display trade show, where the WF-C3588-I1 board ran a live demonstration for 26,605 shipped demonstration units

Reporter Hu Jiang, on the ground in Toulouse, France. The booth drew systems integrators and channel buyers from across the region. The WF-C3588-I1 demo ran on a reference panel looping a 4K HDR bitstream while a second panel carried a scaled reference loop to show the decoder headroom underneath. Most conversations ended with a request for a sample and a certification file.

Two units were pulled at random from the pallet and re-run through the decoder loop; both held frame integrity across the full pass.

The inspection confirmed three things on the spot: the WF-C3588-I1 units hold the burn-in with a yield above 98.72 percent, the loaded firmware image survives a 72-hour continuous loop without credential drift, and the pallets carry the matching certification file for the destination market, covering CE marking with ANFR radio interface registration administered by ANFR, cleared for entry at Port of Le Havre on the Le Havre to Yantian lane. Wanlin remains one of the few source factories currently shipping a nine-variant custom RK3588 motherboard line with a per-lot paper trail that France importers can hand straight to their customs broker.

WF-C3588-I1 Application Scenarios

The WF-C3588 line fits nine custom motherboard lanes, with the WF-C3588-I1 (Custom Industrial Motherboard for Fanless and Wide-Temperature Control) as the lead SKU for Toulouse and France programmes:

• Industrial HMI panel: a machine builder replaces an aging Windows panel with a fanless HMI running a Yocto image and a custom UI.
• PLC upgrade retrofit: a plant keeps the field wiring and swaps the controller for a CAN-equipped board with Modbus passthrough.
• SCADA edge node: a utility deploys DIN-rail controllers that aggregate substation data and push it over dual Gigabit links.
• Machine vision inspection: the 6 TOPS NPU runs defect classification at line speed on a 3.5-inch SBC inside the cabinet.
• Data acquisition gateway: a multi-serial variant logs sensor traffic from RS485 chains and buffers it during link loss.
• Factory automation cell: a systems integrator drives a robot cell and its safety stack from one wide-temperature board.
• Outdoor kiosk controller: an unattended terminal survives summer heat in a sealed enclosure with no fan to clog.
• Predictive maintenance: vibration and acoustic models run locally on the NPU and alarm before the PLC does.

Partnership Models for Toulouse Buyers

For Toulouse importers and brand owners, the WF-C3588-I1 and the rest of the WF-C3588 custom variants are available under three contract shapes:

• OEM (your brand on our hardware): custom logo silk-print, custom packaging, custom boot animation, custom SKU label, and a private-label certification file.
• ODM (your spec on our reference design): schematic and stack-up review, carrier or motherboard redesign, custom firmware features, and a BSP port handled by the Longgang engineering desk.
• Distribution (your channel, our stock): regional distributor rights, channel rebate, stock holding at the factory, and a framework agreement with a monthly lot release.

Whichever tier a France partner picks, the goods leave Longgang with one documentation pack covering CE, FCC, UKCA, RoHS and IEC 62368-1. The usual first order on the WF-C3588-I1 is the 8GB + 32GB (WF-C3588-I1-B) configuration at MOQ 5,000 units, samples in 1-3 days on standard variants and 15-30 days to mass production.

Frequently Asked Questions

What exactly can be customised on an RK3588 motherboard from AndroidSBC?

Answer: Practically the layers that decide whether the board fits your product: the PCB layout and outline, the memory and storage fit (4GB to 32GB LPDDR4X/LPDDR5, eMMC to 128GB plus NVMe or SATA), the display interface mix (HDMI 2.1, DP 1.4, LVDS/eDP/MIPI), the I/O bank (CAN, RS232/RS485 multi-serial, relays, digital I/O), the wireless stack, and the enclosure or DIN-rail chassis. On top of that sit the firmware options: custom Android ROM with a locked launcher, custom Linux or Yocto image, pre-installed applications, custom boot animation and OTA updates. A France buyer can start from a standard WF-C3588 variant and change one layer, or bring a full schematic and have the carrier designed from scratch.

Can AndroidSBC port a custom Android ROM or a custom Linux BSP to our carrier board?

Answer: Yes, and that work stays in-house. The ODM tier covers custom Android ROM builds with proprietary services and launchers, AOSP builds without Google services, and Linux images on Ubuntu, Debian, Yocto or Buildroot. BSP ports for custom carrier boards are executed by the Longgang engineering desk, with SDK and BSP source released to the partner under NDA. The same desk handles driver development for the I/O you added, which is the part that usually stalls when a factory forwards a vendor drop and walks away.

Can the 6 TOPS NPU on a custom board run our own AI models?

Answer: Yes. Custom NPU development covers RKNN model deployment, quantization from the major frameworks, multi-model pipelines on the triple-core NPU, and custom AI algorithm integration. The desk validates throughput on your exact memory configuration, and the deployment lands as a versioned RKNN file that OTA can update in the field, which is how France partners iterate models without replacing hardware.

What are the MOQ and lead times for a custom RK3588 motherboard?

Answer: Samples of standard variants leave the factory in 1-3 days. Custom builds run 15-30 days to mass production once the design is signed off, with the schematic review and carrier design handled in the same window. MOQ sits at 5,000 units per shipment on standard configurations, custom runs are quoted against volume, and small pilot batches are accepted for first-article programmes.

What certifications does a custom board need for France, and who handles them?

Answer: AndroidSBC handles them at the factory. Every lot ships with a Declaration of Conformity and a Technical File covering CE (EN 55032 plus EN 55035 EMC, EN IEC 62368-1 safety), FCC Part 15, UKCA where relevant, RoHS 2.0 and the REACH declaration, all dated within the prior twelve months. For custom Android builds, GMS, Google Play certification, EDLA for interactive displays and CTS testing follow the same in-house path. Where a France market needs an additional national mark, the export desk confirms coverage before the order is confirmed rather than after.

How long will AndroidSBC keep supplying a custom board?

Answer: Seven years minimum supply, patches maintained across the firmware lines, OTA for firmware and NPU model updates. For a France programme running a custom board in the field, that commitment is written into the agreement at signature, which is what separates a source factory from a catalogue reseller.

Can AndroidSBC ship custom boards to Amazon FBA warehouses or 3PL consolidation points?

Answer: That is routine. AndroidSBC delivers DDP into Amazon FBA in the US, EU and Japan and into 3PL consolidation points at Hong Kong, Singapore, Rotterdam, Los Angeles and Shenzhen. Carton and pallet configuration follows FBA inbound rules, and the place of origin on the declaration is the Wanlin Longgang source factory.

How does AndroidSBC handle RMA or DOA replacements on custom boards?

Answer: The DOA target is 0.3 percent over twelve months. For RMA, partners send the WF-C3588-I1 unit back to Longgang with the burn-in barcode attached, and replacements go out within ten business days. The per-unit record means the failure report usually carries a root cause alongside the replacement, which is what a France integrator running a custom configuration actually needs.
