Description
The IO Expansion HAT is a device that is designed to be used with the Raspberry Pi 4B and Raspberry Pi 3B+ microcomputers. The IO Expansion HAT leads out all of the input/output (IO) ports on the Raspberry Pi, including digital, analog, PWM, I2C, UART, SPI, and IIS ports. This allows the user to connect a variety of different sensors, actuators, and other devices to the Raspberry Pi and expand its capabilities.
One of the advantages of the IO Expansion HAT is that it is fully compatible with the DFRobot Gravity Series, which makes it easy for users to connect and set up their projects. This allows the user to focus on building and developing their projects, rather than worrying about complicated connection work. Overall, the IO Expansion HAT is a useful tool for anyone looking to expand the capabilities of their Raspberry Pi microcomputer.
Pinouts
Raspberry Pi GPIO pins work with a maximum logic level of 3.3V. Besides the sensor and module of 3.3V power supply, the product also supports:
- Sensor and module with 5V power supply and 3.3V level
- PWM external power supply (6~12V)
- Controlling multiple servos
