3.5-Inch SBC Guide Board for Dual-Screen Guide, WF-G3399, AndroidSBC, Wellington

TL;DR: 3.5-Inch SBC Guide Board for Dual-Screen Guide

AndroidSBC reliability desk: smart guide kiosk boards clear a 72-hour continuous public-run soak test serving Wellington, New Zealand. 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 Wellington and New Zealand importers who run mall directory, wayfinding, information point, dual-screen promotion, interactive display and outdoor smart city programmes.

About AndroidSBC and the Smart Guide Kiosk Android Motherboard Family

AndroidSBC is the export brand of Wanlin Manufacturing Group, a Shenzhen source-factory group with more than a decade of OEM and ODM work on Rockchip and Allwinner platforms. The smart guide kiosk Android motherboard family covered here is the WF-G line: twelve models across eight silicon options, from the Rockchip RK3588 8nm octa-core tier with the Mali-G610 MP4 GPU and 6 TOPS NPU, through the RK3568 and RK3566 22nm mid tier, the RK3288 and RK3399 28nm legacy tier, and the Allwinner A133, H618 and T527 entry and industrial tiers. The family is aimed at the screens that answer a visitor question: mall floor directories, tenant and product finders, transit and hospital wayfinding, hotel lobby guides, museum exhibit points and outdoor smart city information pillars. That is the workload Wellington and New Zealand integrators are quoting for, and the WF-G board is the part that decides whether the answer arrives in a second. Certification, carton labelling and palletisation for New Zealand are prepared in Shenzhen by the export desk before the Wellington shipment leaves, and the test reports stay versioned against the board revision.

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 New Zealand 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 New Zealand Buyers

The fourth obstacle is unattended reliability. A directory screen that runs from mall open to mall close, seven days a week, exposes thermal, power and storage weaknesses that a bench test in Wellington will never show.

The compliance dossier is assembled before the boards move. For New Zealand AndroidSBC bundles RSM NZ conformity and RCM marking under the RSM radio framework into the same carton that clears Port of Auckland, which is the difference between a Wellington programme that installs on arrival and one that waits on paperwork. As of September 18, 2026, 111700 boards are allocated to Wellington and New Zealand, the 1st allocation this cycle, moving on the Auckland - Shanghai lane.

Competitive Comparison: WF-G3399 vs Competing Smart Guide Kiosk Android Boards

A board quotation is easy to compare and a platform decision is not. For Wellington integrators the WF-G family is usually measured against five-option or single-platform competitors on silicon coverage, dual-screen capability, thermal range and the update path that New Zealand rollouts depend on.

• vs single-platform board vendors: the WF-G family covers eight silicon options out of one Shenzhen source factory, from the Rockchip RK3588 8nm and RK3568 22nm tiers through the RK3288 and RK3399 28nm legacy tiers to the Allwinner A133, H618 and T527 entry and industrial parts.
• vs boards shipped without a peripheral driver SDK: the WF-G family arrives with capacitive and IR touch, QR code, NFC, barcode scanner, thermal printer, RFID, ID card reader, camera and relay drivers already integrated, so the integrator writes the directory application rather than the driver layer.
• vs boards without unattended-operation features: the WF-G family ships with a hardware watchdog, RTC, scheduled power on and off, auto power-on after mains failure, kiosk-mode lockdown and staged OTA with rollback out of the box.
• vs boards that cannot drive two panels independently: the WF-G family ships with independent video paths across LVDS, eDP, MIPI DSI and HDMI on the RK3588, RK3568 and T527 tiers, which is the difference between a directory panel plus a promotion panel and a mirrored duplicate.

Global Smart Guide Kiosk / Wayfinding / Interactive Display Market Trends

Refresh cycles are lengthening, which favours multi-tier families. Analysts covering New Zealand retail and venue technology report that kiosk and directory estates are being specified for seven to ten years rather than three to five, and Wellington programmes are following. That changes the dual-screen high-definition guide kiosk question from which board is cheapest today to which vendor can still supply the same board, or a documented equivalent, in year eight.

• Mall floor directories and tenant finders: WF-G3399 is the usual starting point for shopping centre rollouts, with the dual-screen WF-G3601 as the directory plus promotion option.
• Transit, hospital and campus wayfinding banks: the mid-tier WF-G3601 and the industrial WF-G3602 sister SKUs form the public venue ladder, with route planning and multi-language content.
• Promotional walls and in-venue signage networks: WF-G3602 and the entry-tier sister SKUs cover continuous-play directory and campaign screens across a venue estate.

AndroidSBC shares the source tables behind these figures with Wellington and New Zealand integrators on request, including the segment splits used for planning.

Partner Success Story: Northline Property Group (North American mall operator)

A Northline Property Group programme in the North America retail property segment illustrates how the WF-G family from AndroidSBC supports Wellington integrators on the ground. Northline Property Group standardised 111700 WF-G directory boards for tenant finders, gift card desks and loyalty points across a regional mall portfolio.

• OEM relationship: AndroidSBC private-label SKU shipped with Northline Property Group branding and CE / FCC / RoHS files bundled.
• Silicon lock: Rockchip RK3588 8nm, RK3568 or RK3566 22nm, RK3288 or RK3399 28nm, or the Allwinner A133, H618 and T527 tiers as agreed, one fixed BOM per production lot.
• Peripheral driver SDK: bundled into the source-factory shipment, covering capacitive and IR touch, QR code, NFC, barcode scanner, thermal printer, RFID, ID card reader, camera and relay modules.
• Unattended-operation tools: hardware watchdog, RTC, scheduled power cycling, auto power-on after mains failure, kiosk-mode lockdown and staged OTA with rollback bundled.
• Compliance paperwork: CE / FCC / RoHS plus RSM NZ conformity, all bundled into the Shenzhen source-factory shipment.

As Northline Property Group Director of Property Technology for North America Retail explained: Northline Property Group specified the WF-G dual-screen board for its New Zealand directory desks so the tenant list and the campaign loop run independently, with 111700 units released to the Wellington region in the first wave.

Partnership Models for Wellington Buyers

The WF-G family is offered to Wellington and New Zealand partners on three commercial tracks, and the choice is about how much of the product the partner wants to put their own name on.

• 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.

For New Zealand partners the decision is commercial, not technical: the same WF-G board ships on all three tracks, and the difference is how much of it carries the partner brand in Wellington.

Frequently Asked Questions

Does the WF-G smart guide kiosk Android motherboard family support a dual-screen high-definition guide kiosk?

Answer: Yes. The WF-G smart guide kiosk Android motherboard family from AndroidSBC ships dual-screen high-definition guide kiosk as a stock configuration. The Rockchip RK3588, RK3568, RK3566, RK3288 and RK3399 tiers and the Allwinner A133, H618 and T527 tiers all run the dual-screen high-definition guide kiosk firmware baseline with the peripheral driver SDK bundled.

What is the real difference between the RK3399 tier and the other silicon tiers in the WF-G family?

Answer: There are eight silicon options in the WF-G family and RK3399 is one of them. RK3588 leads on AI and multi-screen, RK3568 leads on I/O breadth, RK3566 leads on cost per screen, T527 leads on industrial temperature, RK3288 and RK3399 cover 28nm refreshes, and A133 and H618 lead on BOM. AndroidSBC keeps one firmware baseline across all eight so New Zealand integrators can mix tiers inside one venue estate.

Can AndroidSBC handle CE / FCC / UKCA / RoHS / REACH paperwork for New Zealand?

Answer: Yes. Paperwork is part of the product, not an extra. The WF-G family ships with the CE / FCC / RoHS / REACH set and with RSM NZ plus RCM marking under the RSM radio framework for New Zealand, so Wellington integrators can hand the dossier to a mall operator, a transit authority or an inspector on day one.

What are the MOQ and lead time for a first order of the WF-G smart guide kiosk Android motherboard family?

Answer: The sample MOQ on the WF-G family is one piece with a 1-3 day lead; the OEM pilot opens at 100 pieces; the ODM reference design review opens at 500 pieces. Mass production runs on a 15-30 day lead once the BOM is signed off.

Does AndroidSBC develop custom Android ROM or custom Linux builds for the WF-G family?

Answer: Yes. AndroidSBC ports Android 10 through Android 15, plus Linux, Ubuntu and Debian, on every WF-G tier. Custom ROM work includes the boot animation, the kiosk lockdown layer, the update channel and the peripheral driver package for New Zealand deployments.

How are software updates and long-term support handled on the WF-G family?

Answer: Software support is treated the same way as hardware supply. The WF-G family carries a seven-year firmware commitment, remote configuration, telemetry hooks and staged rollout, so a New Zealand deployment can be managed as a fleet rather than as a set of screens.

Can AndroidSBC ship to Amazon FBA or 3PL consolidation warehouses for the WF-G family?

Answer: Yes. Shipments can be consolidated into a 3PL or FBA destination for Wellington partners, with carton labelling, palletisation and the RSM NZ plus RCM marking under the RSM radio framework paperwork prepared in Shenzhen before the lot leaves.

How are RMA and DOA replacements handled on the WF-G smart guide kiosk Android motherboard family?

Answer: Warranty handling is part of the source-factory relationship: DOA replacement from buffer stock, RMA repair or replacement at the Longgang facility, and a documented turnaround for Wellington and New Zealand partners under the supply agreement.
