Luckfox Lyra Pi series is a cost-effective Linux development board based on Luckfox Core3506 series modules, designed to provide developers with a simple and efficient development platform. This product supports a variety of high-speed interfaces, including MIPI DSI, RMII, SDIO and USB, which can meet a variety of application scenarios. The low-speed interface adopts Rockchip Matrix IO design, which enables the pins supporting this design to share 98 multiplexing functions, and can freely combine PWM, UART, I2C, SPI and I2S, etc., for rapid development and debugging.
