Case Study: Madrid Corporate AV Procurement Lead Sourcing Success
Lucas Ferreira, a Corporate AV Procurement Lead in Madrid, needed boards that installers could deploy without callbacks and that customs would clear without document chasing. Support calls were climbing because every site used a different board and a different image, so the field team could not keep up.
After two rounds of document checks, Lucas Ferreira selected AndroidSBC as their RK3588 dual display board manufacturing partner. The buyer picked AndroidSBC because the quote included the dual display bring-up and the boot configuration service as standard, not as a paid extra.
- Component traceability: memory, eMMC and power parts come from fixed suppliers and the BOM revision is recorded per batch
- Reliability ratings: wide-temperature validation from -20 to 70 Celsius, with -40 to 85 Celsius industrial options, ESD protection and hardware watchdogs
- Documentation: manuals, interface drawings and quick-start guides in the languages your market needs
The first batch ran around the clock for a month without a single reboot, and the blank screen complaints went quiet.
Problem Analysis & Field Report: Why Global Buyers Need RK3588 Dual Display Smart Classroom Board
Before choosing a dual display board supplier, a buyer should look at what happens after installation: boards that reboot mid-loop, second screens that go blank and certificates that cannot be verified. A university in Madrid found the classroom boards booted to the Android desktop, and students kept exiting the teaching app mid lesson.
Field case: A language school in Madrid used local handwriting recognition on the NPU so stroke feedback stayed instant even when the campus network was slow.
Why it matters for global buyers:
- Separate screens, one board: content and participants or teacher and student panels run from one RK3588 with independent outputs
- Capture path: 4K HDMI RX input brings laptops and cameras into the room without extra hardware
- Timetable automation: scheduled power and app boot follow the class or meeting schedule without IT visits
- Kiosk behavior: boards boot straight into the teaching or meeting app and recover after power loss
- Local AI: NPU handwriting and framing features keep working when the network does not cooperate
Display buyers tend to price a dual display board twice: once on the quote and once in lost screen uptime. A board that shows both screens in the demo but drops the second panel during a 4K loop on a hot afternoon is not cheaper, it is a second purchase in disguise. The same logic applies to frame synchronization, temperature range and document completeness, because each one shows up later as a field visit or a customs hold.

RK3588 Dual Display Board OEM Process: From Inquiry to Shipment
A typical AndroidSBC OEM project begins with the two screens, because panel interfaces, resolutions and mounting decide the carrier layout before anything else. A standard OEM project then follows 8 steps:
- Tell Us Your Target Market - North America, Europe, Middle East, Southeast Asia, East Asia, South Asia, Oceania, Africa or Latin America; different markets may require different certification, OS licensing and connector configurations
- Define the Two Screens - panel models, interfaces, resolutions, orientation and touch needs are fixed against your enclosure and software
- Lock the Software Stack - Android, Ubuntu, Debian, Yocto or Buildroot, plus dual display mode defaults, autostart, kiosk mode and peripheral mapping for your application
- Verify Documentation - for applicable models, request and verify the certificate files, temperature validation and BOM information before ordering
- Sample Evaluation - samples wired to your exact panels are evaluated on your bench or in the field before mass production, with the same BOM used in the approved units
- Confirm Production - after specifications, commercial terms and OEM details are confirmed, the project proceeds to production
- Quality Inspection - boards are inspected and tested with power-on, dual-output display, touch and 48-hour aging procedures according to applicable production and quality-control standards
- Shipment - products are prepared for shipment FOB, CIF or DDP according to the agreed logistics requirements
Customer Testimonials
Buyers who moved from two player boxes per site to single-board dual display designs describe the difference in uptime and paperwork:
- Lucas Ferreira (Corporate AV Procurement Lead, Madrid, Spain): "Extended mode surviving reboots was the whole reason we switched; the old boards dropped the second screen every time power flickered."
- Olivia Ashworth (QSR Chain IT Manager, Singapore, Singapore): "Extended mode surviving reboots was the whole reason we switched; the old boards dropped the second screen every time power flickered."
- Sophie Delacroix (POS Terminal Product Manager, Warsaw, Poland): "The panel timing review saved us from a connector mistake that would have cost a full board revision."
Frequently Asked Questions
Q: How do two screens help a lesson?
A: The teacher keeps the main whiteboard for teaching and uses the second screen for student exercises, group answers or a document camera, without switching away from the lesson.
Q: Can the board follow a school timetable?
A: Scheduled power on/off follows the class schedule, and the board boots into the teaching app with the correct room profile.
Q: Is handwriting recognition local?
A: On supported builds the NPU handles handwriting strokes locally, so recognition works without sending student data off site.
Q: Which touch technology fits schools?
A: Infrared touch survives pens, fingers and pointers, while capacitive gives a smoother writing feel. Both options run on the same board family.
Q: What support do distributors get?
A: Region-specific firmware, language packs, spares and a document pack for tenders are provided per project.
