Product description: IO Expansion HAT - lead expander for Raspberry Pi Zero/Zero W - DFRobot DFR0604
An overlay for the minicomputer Raspberry Pi Zero / Zero W version, on which individual Raspberry Pi pinout sections have been separated. The module offers digital, analog, I2C, PWM, UART and SPI ports. Additionally, analog and PWM ports are brought out by built-in STM32 MCU module which allows communication with Raspberry Pi via I2C interface. With the libraries provided, the user is able to conveniently control the PWM output as well as read analog data. The overlay supports 5 V power supply and 3.3 V sensors. The PWM ports can be powered from an external source ranging from 6 V to 12 V or by the Raspberry Pi (5 V).
