TL;DR: Commercial Multi-Screen Video Wall Board
Chicago, United States - September 10, 2026. A 22,835-unit consignment of WF-RK3588S boards left the Wanlin Longgang source factory for Chicago this week, the 241st production lot released on the Rockchip RK3588 line.
AndroidSBC customs and certification briefing for Allwinner and Rockchip board shipments serving Chicago, United States. The WF-Series is a nine-board line rather than a single part number, and the shape is deliberate. Allwinner A133, H618, and T527 cover cost-sensitive display, OTT and Android TV, and industrial edge inference; Rockchip RK3588, RK3568, RK3566, and RK3288 cover 8K video wall, industrial edge, machine vision, and POS; WF-A133S and WF-RK3588S are SOM modules for carrier-board projects. A Chicago buyer can hold one supplier file, one documentation format, and one MOQ structure across every tier it sells.
Global SMARC and COM Express Module Engineering Market Trends
- SMARC module design: WF-RK3588S seats on the 314-pin MXM edge with the carrier holding the I/O.
- Display and signage refresh cycles: a longer content loop and a higher panel resolution now define the refresh trigger. The WF-RK3588S board carries that headroom without a board change.
- Edge AI boxes: WF-RK3588S runs 6 TOPS NPU inference on the carrier-side thermal solution.
The read across the SMARC and COM Express Module Engineering channel is that buyers are consolidating suppliers: fewer vendors, wider platform coverage per vendor, and a longer contract behind each order.
Read together, the three patterns explain the move in Chicago from spot quotes to framework agreements released monthly, which is what a retail or hospitality programme needs to hold a twelve-month shipping window without a mid-year break.
WF-RK3588S Application Scenarios
The WF-Series fits nine application lanes, with the WF-RK3588S (SOM Module and SMARC Carrier Board) as the lead SKU for Chicago and United States programmes:
- SMARC module design: WF-RK3588S seats on the 314-pin MXM edge with the carrier holding the I/O.
- COM Express Type 6 builds: WF-RK3588S maps to the Type 6 pin-out for existing x86 carriers.
- Edge AI boxes: WF-RK3588S runs 6 TOPS NPU inference on the carrier-side thermal solution.
- Video wall controllers: WF-RK3588S drives HDMI 2.1 and DP 1.4 out through the carrier.
- Medical imaging terminals: WF-RK3588S pairs PCIe 3.0 x4 with the carrier frame grabber.
- Autonomous vehicle compute: WF-RK3588S holds -40C to 85C on the automotive-grade carrier.
- Bespoke industrial carriers: WF-RK3588S ships the signal integrity report for the customer stack-up.
- Carrier bring-up: WF-RK3588S comes with the BSP port for the carrier revision.
What is the difference between the nine WF-Series models?
Answer: Nine boards, seven silicon platforms, two of them modules. WF-A133 and WF-H618 and WF-T527 are the Allwinner entries for commercial display, OTT TV, and industrial edge respectively. WF-RK3588, WF-RK3568, WF-RK3566, and WF-RK3288 are the Rockchip entries for 8K video wall, industrial edge, machine vision, and POS. WF-A133S and WF-RK3588S are board-to-board SOM modules sized for customers who want to design the carrier themselves. Each board carries three memory configurations.
Does AndroidSBC support custom Android ROM or custom Linux development?
Answer: Yes. Under NDA, AndroidSBC delivers custom Android ROM work with proprietary services, custom Linux images on Yocto or Debian or Buildroot, and BSP ports for customer carriers. The engineering desk at Longgang performs the port itself, which matters because an unmodified vendor BSP rarely matches a customer carrier revision.
What about software updates and long-term support?
Answer: Seven years minimum supply, with security patches maintained across the Android and Linux firmware lines. Partners who deploy at scale can use the AndroidSBC OTA infrastructure to update field units. For long-lifecycle programmes in POS, signage, or industrial control, the support term is written into the framework agreement at signature.
Can AndroidSBC ship 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, and Los Angeles. 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?
Answer: AndroidSBC targets a 0.3 percent DOA rate across the WF-Series, measured over the prior twelve months. On RMA, the partner returns the faulty WF-RK3588S unit to Longgang with its burn-in barcode, and a replacement ships within ten business days. Because the burn-in record is attached per unit, the failure analysis normally comes back with a root cause rather than a credit note.
