Zero W Mini Linux Development Board Based on RK3506B Chip, Integrated with Triple-Core Arm -A7 Zero W is a Linux mini development board powered by the Rockchip RK3506B to provide a simple and efficient development platform for developers. Onboard multiple high-speed interfaces including MIPI , SDMMC, USB, etc. to meet application scenarios. The low-speed interfaces utilize Rockchip Matrix IO design which supports multiplexing 98 function signals on GPIO pins, allows for flexible configuration of interfaces like PWM, UART, I2C, SPI, and I2S for quick development and debugging. Integrated wireless communication module, suitable for IoT communication scenarios such as smart home and industrial control. Triple-core ARM -A7 32-bit core, with integrated to support single-precision and double-precision floating-point operations. Built-in ARM -M0 MCU design, supports and AMP configuration. Supports DDR3L memory interface expansion, meeting expansion needs. The low-speed interfaces adopt Rockchip Matrix IO design, which allows rich function signals to share the limited chip pins, making peripheral circuit adaptation more flexible. Supports multiple audio inputs and outputs, providing high-quality audio playback and recording functions.
