It is pretty small and perfectly suitable for Raspberry Pi 5 Zero Zero W. The board leads out the I O ports on Raspberry Pi including I2C, UART, SPI and digital, among which the digital ports are led out via the GPIO16~GPIO25(BCM) of Raspberry Pi, so these ports can be directly used. Besides, the PWM and Analog ports are led out through the on
