TL;DR: Commercial Multi-Screen Video Wall Board
SHENZHEN, China, September 10, 2026 - The WF-A133S board cleared the Longgang aging bench this week in lot 240, a 9,930-unit run for Los Angeles, United States, and moved straight to the container yard.
AndroidSBC export paperwork update on the nine-model WF-Series board line serving Los Angeles, United States. What United States importers get from the WF-Series is platform breadth from one factory. Three Allwinner parts and four Rockchip parts sit under one part-number scheme, with two SOM modules for customers who design their own carrier. Wanlin builds all nine at Longgang in Shenzhen, and the export desk issues one certification pack per lot covering CE, FCC, UKCA, RoHS, and REACH.
WF-A133S Technical Specifications
| Parameter | AndroidSBC WF-A133S (Core Board SOM and Custom Carrier Board) | Industry Average |
|---|---|---|
| Processor | Allwinner A133 quad-core ARM Cortex-A53 1.5GHz 64-bit + PowerVR GE8300 GPU on a 200-pin B2B SOM | Discrete motherboard only, no SOM option |
| Process node | 22nm low-power | 28nm-40nm mixed |
| GPU | PowerVR GE8300 (OpenGL ES 3.2, OpenCL 1.1) | Mali-400 MP2 |
| Video decode | H.265 4K@30fps + H.264 4K@30fps hardware decode | 1080p@60fps hard limit |
| SOM footprint | 45mm x 45mm board-to-board module with 200-pin connector | Full-size ATX or mini-ITX only |
| Memory | 2GB LPDDR4 onboard (4GB optional) | DDR3 1GB |
| Storage | 8GB / 16GB / 32GB eMMC 5.1 onboard | 4GB-8GB NAND |
| Carrier interface | LVDS + MIPI-DSI + RGB + UART / GPIO / I2C / SPI broken out to the carrier | Fixed I/O, no carrier breakout |
| Power design | Single 5V input with onboard PMIC, carrier-side power sequencing documented | Multi-rail custom power tree required |
| Wired network | Gigabit Ethernet + Mini PCIe 4G LTE on the reference carrier | 100M Ethernet only |
| Design service | Schematic review, carrier PCB layout, BSP porting, thermal simulation | Board-only supply, no engineering service |
| OS support | Android 10 + Linux (Ubuntu 20.04 / Debian 11) with carrier BSP port | Vendor image only |
All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-A133S (Core Board SOM and Custom Carrier Board) 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 2GB + 16GB, 200-pin B2B (WF-A133S-A) variant is the typical configuration for the custom carrier board and SOM integration use case, with a sustained weekly capacity of 5,000 pcs/wk on the Longgang line.
Challenges in Sourcing Core Board SOM and Custom Carrier Board for United States Buyers
Buyers in Los Angeles who have run the core board som and custom carrier board category for a few years tend to stop shopping on price alone. The Allwinner A133 allocation is the real constraint, and it is the reason a 9,930-unit order can look cheap on paper and expensive in a slipped quarter. Then comes the firmware question. The hardware spec is straightforward to verify; whether the board holds a credential-locked stack through a 72-hour loop and a field OTA is a different test, and it is normally the Los Angeles buyer's warehouse that discovers the answer.
On the United States side, the destination file matters as much as the board specification. In the United States FCC Part 15 authorisation is required and an FCC ID applies to radio modules, while UL or ETL listing is usually demanded by the retail channel. The export desk prepares the destination-market file covering FCC Part 15 authorisation with an FCC ID for radio modules and a UL or ETL listing, administered by FCC / UL, and releases it with the standard multi-market pack (CE, FCC, UKCA, RoHS, REACH). The lot is booked into Port of Los Angeles on the Los Angeles to Yantian lane.
WF-A133S Application Scenarios
The WF-Series fits nine application lanes, with the WF-A133S (Core Board SOM and Custom Carrier Board) as the lead SKU for Los Angeles and United States programmes:
- Custom carrier board design: WF-A133S plugs the SOM into the customer carrier over the 200-pin B2B connector.
- Industrial panel builds: WF-A133S feeds the LVDS panel from the carrier-side connector.
- Medical device carriers: WF-A133S documents the power sequencing for the carrier PMIC tree.
- Vending machine control: WF-A133S breaks the multi-COM path out to the vending controller.
- Access control: WF-A133S exposes UART and GPIO for the reader and lock interface.
- Bespoke kiosk hardware: WF-A133S pairs the RGB interface with the carrier touch controller.
- SOM integration: WF-A133S ships with the BSP port for the customer carrier revision.
- Industrial HMI: WF-A133S runs the Android 10 UI on the customer enclosure.
Partnership Models for Los Angeles Buyers
AndroidSBC opens the WF-Series to United States partners through three structures, and a single agreement can draw on more than one:
- 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.
Does the WF-Series support certified Android TV or Google Mobile Services?
Answer: Yes, on the platforms where that matters. The WF-H618 runs Android 12 (ATV 12) with Google Mobile Services and is ready for Android 14 (ATV 14). AndroidSBC burns the GMS, Widevine L1, and Dolby Audio stack at the Longgang plant on every production lot, so the board ships ready for Netflix, Disney Plus, Amazon Prime Video, HBO Max, Apple TV, and YouTube TV. The commercial and industrial boards in the line use the AOSP image with an optional GMS build for partners who need it.
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.
Can AndroidSBC handle CE, FCC, UKCA, RoHS, and REACH paperwork for United States?
Answer: That is handled in-house. Each lot leaves Longgang with a Declaration of Conformity and a Technical File holding the CE, FCC Part 15, UKCA, RoHS 2.0, and REACH documents, all dated inside twelve months. For United States specifically, AndroidSBC will confirm at quotation stage which marks apply and whether a local variation is required, so the paperwork question is settled before production rather than at the port.
What are the MOQ and lead time for a first order?
Answer: MOQ is 5,000 units per shipment for the standard memory configuration of any WF-Series board. Sample lead time runs four weeks and mass production six weeks. Partners who prefer a twelve-month blanket order with a monthly lot release can negotiate the MOQ down, and mixed-platform orders on one purchase order are accepted.
Does AndroidSBC support custom Android ROM or custom Linux development?
Answer: Yes, under NDA. ODM partners get custom Android ROM work including proprietary services and a custom launcher, Linux builds based on Yocto, Debian, or Buildroot, and BSP ports for custom carrier boards. The SDK and BSP source are released to the partner under the NDA, and AndroidSBC's engineering desk handles the port rather than handing over an unmodified vendor drop.
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-A133S 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.
