The LicheeRV Nano is a mini-sized development board (measuring only 22.86*35.56mm), equipped with the SG2002 processor the same as the Milk-V Duo 256M.
It features a powerful core running at 1GHz (RISC-V/ARM options available) and a smaller core at 700MHz RISC-V, along with 256MB DDR3 memory, and an integrated 1Tops NPU. The board includes a wealth of interfaces such as MIPI-CSI, MIPI-DSI, SDIO, ETH, USB, SPI, UART, I2C, etc., allowing for the expansion of a wide variety of applications.
Its through-hole/half-hole design facilitates easy mass production and soldering.
NOTE: This variant does not include wifi, ethernet, or camera
