Oz64

The Oz64 SBC

The Oz64 3D model

The Oz64 is a low cost single-board computer based on the Sophgo SG2000 SoC with dual T-Head C906 64-bit RISC-V cores, an ARM Cortex A53 64-bit RISC CPU core and an 8051 8-bit core supported by 512 MB of embedded DRAM memory, with WiFi and Bluetooh radio interfaces. The Oz64 SBC comes in a model-B form-factor, has a microSD card slot, an eMMC plugin connector, an USB 2.0 Type-A host port, and many other peripheral interfaces for makers to integrate with sensors and other devices.
