Plus is a mini Linux development board based on Rockchip RK3506G2 chip, designed to provide developers with a simple and efficient development platform. This product supports a variety of high-speed interfaces, including MIPI , RMII 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., which is convenient for rapid development and debugging. Tri-core ARM -A7 32-bit core with integrated , supporting single-precision and double-precision floating-point operations. Built-in ARM -M0 MCU design, supports and AMP configurations. Built-in 128MB DDRL3 to meet the application requirements of multi-core operation. The low-speed interface adopts Rockchip's Rockchip Matrix IO design, which allows a variety of multiplexing functions to share limited chip pins, making peripheral circuit adaptation more flexible. Built-in audio and video codecs, support for multiple audio input and output, and provide high-quality audio playback and recording functions.
