TL;DR: Industrial 3.5-Inch SBC Board
Houston, United States - September 10, 2026. The 196th WF-H618 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 WF-Series against the previous board generation serving Houston, United States. The line runs from the Allwinner A133 display board at the entry tier up to the Rockchip RK3588 eight-core board for video wall and AI work, with the Allwinner T527 octa-core board and the Rockchip RK3568, RK3566, and RK3288 filling the industrial, vision, and POS tiers between them. AndroidSBC ships the whole range from the Wanlin Longgang plant, and Houston buyers can mix platforms inside a single framework agreement rather than opening a new supplier file for each tier.
WF-H618 Technical Specifications
| Parameter | AndroidSBC WF-H618 (OTT TV Box and Android TV Board) |
|---|---|

| Process node | 28nm low-power |

| Video decode | H.265 8K@24fps + H.264/VP9/AVS2 4K@30fps hardware decode |
| Video encode | H.264 4K@25fps + JPEG 1080p@60fps |
| Display output | HDMI 2.0 4K@60fps + CVBS OUT |
| HDR | HDR10 / HDR10+ / HLG / HDR Vivid |
| Memory | 2GB / 4GB LPDDR4 |
| Storage | 8GB / 16GB / 32GB eMMC 5.1 onboard |
| Wireless | WiFi 6 + Bluetooth 5.0 BLE module |
| Wired network | 10/100/1000M Gigabit Ethernet + USB 2.0 HOST/OTG |

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-H618 (OTT TV Box and Android TV 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 + 8GB (WF-H618-A) variant is the typical configuration for the OTT TV box and Android TV stick use case, with a sustained weekly capacity of 5,000 pcs/wk on the Longgang line.
Global OTT Set-Top Box and Android TV Market Trends
- OTT TV box: WF-H618 runs the ATV 12 launcher with the GMS stack pre-burned.
- Display and signage refresh cycles: a longer content loop and a higher panel resolution now define the refresh trigger. The WF-H618 board carries that headroom without a board change.
- Streaming media player: WF-H618 holds an 8K H.265 loop while the 4K HDMI 2.0 output stays locked at 60fps.
What the OTT Set-Top Box and Android TV 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 retail or hospitality programme needs to hold a twelve-month shipping window without a mid-year break.
WF-H618 Application Scenarios
The WF-Series fits nine application lanes, with the WF-H618 (OTT TV Box and Android TV Board) as the lead SKU for Houston and United States programmes:
- OTT TV box: WF-H618 runs the ATV 12 launcher with the GMS stack pre-burned.
- Android TV stick: WF-H618 fits the 56x85mm dongle envelope with the IR receiver onboard.
- Streaming media player: WF-H618 holds an 8K H.265 loop while the 4K HDMI 2.0 output stays locked at 60fps.
- Hybrid set-top box: WF-H618 pairs the Gigabit Ethernet port with the USB 2.0 OTG path.
- Hotel IPTV receiver: WF-H618 accepts property-wide APK plus DRM credential push.
- Smart screen: WF-H618 drives the MIPI-DSI panel through the 26-pin expansion header.
- Single board computer: WF-H618 boots Debian, Ubuntu, and Armbian from the same image set.
- IoT gateway: WF-H618 runs the Matter-ready stack on OpenWrt 23.
Partnership Models for Houston Buyers
Three commercial structures are open to Houston buyers on the WF-H618 and the rest of the WF-Series:
- 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-H618 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.
