Zero W 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 , SDMMC 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, which is convenient for rapid development and debugging. Integrated wireless communication module, suitable for IoT communication scenarios such as smart home and industrial control model: Zero W processor:Triple-core Arm -A7 (1.2GHz) + Arm -M0 Memory:Onboard 512MB DDR3L USB:Native USB OTG2.0 x 1,HUB expansion USB HOST2.0 x 2 screen interface:2- MIPI GPIO:28 Rockchip Matrix IO Pins Default storage medium:SPI NAND FLASH (256MB) Wireless communication:Onboard 2.4GHz Wi-Fi 6 / Bluetooth 5.2 / BLE (The product printed words depending on the batch, but this does not affect use) Color: As Shown Material: PCB Package Contents: 1 * Board Only the above package content, other products are not included.
