1. for Pico GPIO sensor expansion board is specially designed for Pico of Raspberry Pie. It adopts a direct plug-in design and leads out all pins of Pico development board.2. The expansion board carries 3.3V and 5V indicators, and provides reset keys.3. The expansion board classifies Pico peripheral interfaces for Raspberry Pie, which are arranged as follows: IIC interface, serial interface, SPI interface, SWD interface; It also provides special interfaces for common modules, such as OLED display interface, Bluetooth module interface and steering drive interface.4. Plug and play, no separate supply, suitable for in-depth learning and development of Pico for raspberry pie5.
