Key Engineering Highlights
- Compresses an 8-core RK3588S2 SoC, 6-TOPS NPU, 16GB RAM, 64GB eMMC, and 2×2 MIMO PCIe Wi-Fi 6 onto a 25-gram, 5.7mm-thick board smaller than a credit card (82×57.5mm)
- Exposes three 4-lane MIPI CSI camera interfaces and four independent display buses (HDMI 2.1, USB-C DP 1.4, and dual MIPI DSI) via high-density low-profile FPC connectors for UAVs and wearables
- Integrates a dedicated STM32 microcontroller and SPI-flash OOWOW service that downloads and flashes Ubuntu, Android, or Debian directly over Wi-Fi without an SD card
