TL;DR: RK3588 Custom SOM Development Kit
Houston, United States - September 12, 2026. The 196th WF-C3588-I1 shipment left Shenzhen for Houston this week with 10,655 units aboard, after a full burn-in cycle and a destination-market document check.
AndroidSBC head-to-head comparison of the custom RK3588 motherboard platform serving Houston, United States. 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 Houston buyers can mix custom variants inside a single framework agreement rather than opening a new supplier file for each product line.

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 United States 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.
Global Custom Industrial Motherboard and Panel PC Market Trends
- 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 Houston buyers increasingly weight supplier continuity above a marginal price difference.
Read together, the three patterns explain the move in Houston from spot quotes to framework agreements released monthly, which is what a custom RK3588 motherboard programme needs to hold a twelve-month shipping window without a mid-year break.
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 Houston and United States 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 Houston Buyers
Three commercial structures are open to Houston buyers on the WF-C3588-I1 and the rest of the WF-C3588 custom variants:
- 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.
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 United States 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. Under NDA, AndroidSBC delivers custom Android ROM work with proprietary services and a locked launcher, custom Linux images on Ubuntu, Debian, Yocto or Buildroot, BSP ports for customer carriers, and driver development for project-specific I/O. Source access is released to the partner, and the port is performed at Longgang, which matters because a vendor BSP rarely matches a custom carrier revision on the first try.
Can the 6 TOPS NPU on a custom board run our own AI models?
Answer: The NPU is fully open on the custom line. Bring the model in PyTorch, ONNX, TensorFlow or Caffe and the Longgang desk handles the RKNN quantization, the runtime integration and the validation against your board's thermal and memory profile. Custom AI algorithm integration is a standard line item on the ODM scope, and the resulting model ships embedded in the firmware image burned per lot.
What are the MOQ and lead times for a custom RK3588 motherboard?
Answer: Standard-variant samples ship in 1-3 days from stock, so your engineering team can start integration while the custom scope is being quoted. A custom run follows a 15-30 day mass-production window after schematic and stack-up sign-off. MOQ is 5,000 units per shipment on standard variants; on custom configurations the MOQ is negotiable against volume commitments, and small batch orders are accepted for pilot phases. A twelve-month framework agreement with monthly lot releases brings the per-lot MOQ down further.
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 United States 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: Yes, including DDP into Amazon FBA in the US, EU and Japan, plus 3PL consolidation points in Hong Kong, Singapore, Rotterdam, Los Angeles and Shenzhen. Cartons are labelled to FBA inbound spec and the declaration names Longgang as the origin. Partners who consolidate in Hong Kong usually take FOB Yantian and handle the last leg themselves.
How does AndroidSBC handle RMA or DOA replacements on custom boards?
Answer: AndroidSBC targets a 0.3 percent DOA rate across the WF-C3588 line, measured over the prior twelve months. On RMA, the partner returns the faulty WF-C3588-I1 unit to Longgang with its burn-in barcode, and a replacement ships within ten business days. Because the burn-in record and the configuration file are attached per unit, the failure analysis normally comes back with a root cause rather than a credit note, which matters when a custom configuration is holding up a production line.
