Luckfox Lyra Ultra series is a micro Linux development board based on Rockchip RK3506B chip, designed to provide developers with a simple and efficient development platform. This product supports a variety of high-speed interfaces, including MIPI DSI, RMII, DDR and USB, which can meet a variety of application scenarios. The low-speed interface adopts Rockchip Matrix IO design, so that the pins supporting this design share 98 multiplexing functions, and can freely combine PWM, UART, I2C, SPI and I2S, etc., which is convenient for rapid development and debugging.
