Introduction
This micro development board is specially designed to run Linux. Despite a mini body, it has all the vital functions. Equipped with F1C200S as the maincontroller chip, the board offers various commonly-used peripheral ports: GPIO, I2C & SPI, SDIO, Audio port(record, play), Video(RGB565 Display, touch, DVP), USB Host, OTG, etc. Besides, the board comes with a built-in 64MB DDR and onboard 128MB Nand Flash, which fully supports Linux ecology and running complete Python.
Currently, this product is fully open source so that users are allowed to compile any module according to their own requirements. However, it’s mainly for Python developers and senior enthusiasts as it’s a little difficult to get started.
