For Pi is a cost-effective Linux development board based on the Core1106 series module of for Technology, to provide developers with a simple and efficient development platform. Supports multiple interfaces, such as MIPI , GPIO, UART, SPI, I2C, USB and 4G module M.2, etc., suitable for various embedded application development. Onboard 2.4GHz Wi-Fi6 and Bluetooth 5.2 or BLE Bluetooth modules, stable connection and efficient transmission. PoE module interface is reserved, and the power supply method of the development board is more flexible. USB expansion: flexibly switch USB-C or 4 xUSB-A HOST interface through the dip switch. 4G module M.2 interface: The USB-A-4 interface can be switched to the 4G module M.2 interface through the dip switch, supporting the 4G module SIM7600G-H-M.2. Audio interface: patch microphone and microphone expansion interface and 3.5mm audio output interface, meeting a variety of audio application scenarios.
