Oz64

The Ox64

Powered by RISC-V

The Ox64 is a RISC-V based single-board computer based on the Bouffalo Lab BL808 RISC-V SoC with C906 64-bit and E907/E902 32-bit CPU cores supported by 64 MB of embedded PSRAM memory, and with built-in WiFi, Bluetooh and Zigbee radio interfaces. The Ox64 comes in a breadboard-friendly form-factor, has a microSD card slot, a USB 2.0 Type-C port, and many other peripheral interfaces for makers to integrate with sensors and other devices.
