Boardcon Tiny1126B shrinks the company’s MINI1126B-P Rockchip RV1126B system-on-module (SoM) from 38x30mm to 34x30mm, targeting even more compact AI vision systems such as smart cameras, smart door locks, inspection cameras, cleaning/logistics robots, DMS (Driver Monitoring Systems), BSD (Blind Spot Detection) solutions, and smart displays.
Despite its smaller size, the Tiny1126B features two 0.4mm pitch 100-pin connectors, instead of two 0.5mm pitch 80-pin connectors for its predecessors, offering even more I/Os. It’s notably gaining a USB 3.0 DRD (Dual-Role Device) interface, an extra SDMMC interface, one additional SPI and I2C interfaces, Fast Ethernet, and more. The rest of the specifications, including memory capacity (up to 4GB LPDDR5) and storage (up to 256GB eMMC flash), remain the same.
