TL;DR: Shopping Mall Guide Kiosk Board
AndroidSBC field desk: guide kiosk rollout map updated across retail, transport, healthcare and hospitality venues serving international market, United States. The WF-G3399 smart guide kiosk Android motherboard spans the dual-screen high-definition guide kiosk and eleven sister models in the WF-G series, all built on the RK3399 dual Cortex-A72 1.8GHz plus quad Cortex-A53 64-bit SoC with the ARM Mali-T860 MP4 GPU, dual HDMI 2.0 4K output plus eDP, and Android 11 firmware support. AndroidSBC, the export arm of Wanlin Manufacturing Group, ships the WF-G family from the Longgang source factory in Shenzhen to international market and United States importers who run mall directory, wayfinding, information point, dual-screen promotion, interactive display and outdoor smart city programmes.

WF-G3399 Technical Specifications

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-G3399 (dual-screen high-definition guide kiosk) maintains its 4K HDMI output plus capacitive touch sampling while running the burn-in test loop, a configuration that competing single-platform boards cannot sustain at 60fps. For United States importers sourcing the WF-G family, the WF-G3399-A variant is the typical configuration for the hotel lobby and resort directory terminal use case, with a sustained weekly capacity of 5000 pcs/wk.
Challenges in Sourcing Smart Guide Kiosk Android Motherboards for United States Buyers
The first obstacle for United States buyers is specification drift. A datasheet says RK3588 or RK3568, but the board that shows up on the international market loading dock has different memory, a different display interface or a different Android build than the sample that was approved.
Working with the source factory removes the middle layer. United States integrators reach the AndroidSBC engineering desk directly, international market specification changes go into the next layout revision instead of into a negotiation, and failure analysis for any WF-G lot is completed by the FCC Part 15 and FCC ID for radio modules, plus UL or ETL safety listing line that produced it, with FCC / UL conformity files on record for Port of international market. On the international market - Shanghai lane, 138000 boards are committed for international market and United States as of September 18, 2026; AndroidSBC counts this as the 3rd release window on the family.
WF-G3399 Application Scenarios
The WF-G3399 dual-screen high-definition guide kiosk sits inside a twelve-variant WF-G smart guide kiosk Android motherboard family from AndroidSBC, a Wanlin Manufacturing Group export brand. The WF-G3399-A configuration is the typical build for the hotel lobby and resort directory terminal use case, with payment-peripheral driver SDK and OTA content management bundled.
- Shopping centre floor directories and tenant finders: WF-G3399 plus WF-G8800 form the mall-side directory ladder, with independent dual display output and 4K HDMI.
- Compact countertop enquiry and price check terminals: WF-G8801 plus WF-G3399 are the usual pairing where housing depth is limited and the BOM target is fixed.
- Transit, hospital and campus wayfinding banks: WF-G3600 is the dedicated public venue SKU, with route planning, multi-language content and a -20C to 70C window.
- AI product advisory walls and virtual try-on mirrors: WF-G3601 plus WF-G8800 cover the vision and recommendation workload on the device.
- Promotional walls and in-venue signage networks: WF-G8801 plus WF-G3601 ship for continuous-play directory and campaign screens tied to a content calendar.
- Hotel, resort and casino lobby directories: WF-G8800 plus WF-G3600 carry the guest orientation flow in international market.
- Exhibition and museum interpretive display points: WF-G3399 is the compact SKU for exhibit-side content and catalogue browsing.
- Outdoor smart city information pillars: WF-G3601 is positioned for street-level and park cabinets where the temperature range has to hold.
- Venue programmes running in international market: mall directories, supermarket price check, pharmacy enquiry, transit wayfinding, hospital orientation, hotel lobby guides, museum exhibits, campus directories and outdoor information pillars.
Partnership Models for international market Buyers
Entry into the WF-G family is available on three tracks for international market and United States buyers, and they are designed so a partner can move between them without re-qualifying the platform.
- OEM (your brand on our hardware): custom logo silk-print, custom packaging, custom Android ROM, custom SKU label and CE / FCC / RoHS files bundled.
- ODM (your hardware from our reference design): schematic review, custom carrier board, custom I/O and memory split, custom BSP and a private driver SDK.
- Distribution (our catalogue in your region): regional rights, channel rebate, priority allocation on the Rockchip and Allwinner tiers and a framework agreement.
One production line in Longgang serves all three tracks, so a international market partner who starts on the distribution track and later commissions an ODM design stays on the same United States supply chain.
Does the WF-G smart guide kiosk Android motherboard family support a dual-screen high-definition guide kiosk?
Answer: Yes. The WF-G family ships dual-screen high-definition guide kiosk as a stock configuration on Rockchip and Allwinner silicon alike, flashed and functionally tested at the Wanlin Longgang source factory before the lot leaves the line for United States.
What is the real difference between the RK3399 tier and the other silicon tiers in the WF-G family?
Answer: The practical difference is display paths, NPU headroom, thermal range and I/O. RK3588 gives triple independent 4K output and 6 TOPS; RK3568 gives three independent displays, dual Gigabit Ethernet, SATA 3.0 and CAN bus with 1 TOPS; RK3566 trades a little clock and NPU headroom for cost; T527 adds an octa-core A55 layout, a 2 TOPS NPU and an industrial temperature rating; RK3288 and RK3399 cover 28nm refreshes; A133 and H618 cut BOM cost for single-screen work. AndroidSBC maps RK3399 to the deployment rather than to the headline.
Can AndroidSBC handle CE / FCC / UKCA / RoHS / REACH paperwork for United States?
Answer: Yes. The Longgang factory keeps the CE, FCC, RoHS and REACH declarations on file for the WF-G family and adds FCC / UL plus FCC Part 15 and FCC ID for radio modules, plus UL or ETL safety listing for United States shipments. international market importers receive the full dossier with the first lot, not after it.
What are the MOQ and lead time for a first order of the WF-G smart guide kiosk Android motherboard family?
Answer: For international market and United States buyers the entry ladder on the WF-G family is a single sample board at 1-3 days, a private-label pilot from 100 pieces, and an ODM design programme from 500 pieces, with 15-30 day mass production once the specification is frozen.
Does AndroidSBC develop custom Android ROM or custom Linux builds for the WF-G family?
Answer: Yes. Firmware customisation is handled by the same engineers who keep the reference BSP, so a international market request for a custom launcher, a locked kiosk mode or an added peripheral driver goes into the maintained branch rather than into a one-off fork.
How are software updates and long-term support handled on the WF-G family?
Answer: AndroidSBC commits to a seven-year firmware update window on the WF-G family. In practice that means security patches, driver updates and content client updates are published on a maintained branch, and international market integrators choose when to take them.
Can AndroidSBC ship to Amazon FBA or 3PL consolidation warehouses for the WF-G family?
Answer: Yes. AndroidSBC handles FBA and 3PL consolidation for the WF-G family, including serialised carton labels, pallet plans and the FCC / UL documentation set for United States customs at Port of international market.
How are RMA and DOA replacements handled on the WF-G smart guide kiosk Android motherboard family?
Answer: RMA and DOA are handled at the source. DOA boards are replaced from Shenzhen buffer stock on photo or video evidence, and RMA units are repaired or replaced at the Longgang facility with a defined turnaround written into the supply agreement.
