The Luckfox Lyra Pi is a cost-effective Linux micro development board, based on the Luckfox Core3506 chip, designed to provide a simple and efficient development platform for developers. It features multiple high-speed interfaces including MIPI DSI, RMII, SDIO, and USB to meet various application scenarios. The low-speed interfaces utilize Rockchip Matrix IO design, which supports multiplexing 98 function signals on GPIO pins, allowing for flexible configuration of interfaces like PWM, UART, I2C, SPI, and I2S for quick development and debugging.
