Revision as of 08:35, 21 October 2022
The Ox64 is a RISC-V based Single Board Computer powered by Bouffalo Lab BL808 C906 64-Bit RISC-V CPU, 32-Bit CPU, embedded 64MB PSRAM memory and build-on 3 radio RF (Wifi, BT, Zigbee). It provides breadboard friendly form factor, MicroSD Card slot, USB 2.0, and many other peripheral interfaces for makers to integrate with sensors and other devices.

- Disclaimer: Please note that PINE64 SBC is not a "final" product and in general certification is not necessary. However, PINE64 still submits the SBC for FCC, CE, and ROHS certifications and obtain the certificates to prove that the SBC board can pass the testing. Please note, a final commercial product needs to perform its own testing and obtain its own certificate.
