IO Expansion HAT for Raspberry Pi 4B/3B+

This IO Expansion HAT from DFRobot is the perfect companion for your Raspberry Pi 4B/3B+! It leads out all of the IO ports on Raspberry Pi including digital port, analog port, PWM, IIC, UART, SPI, and IIS. Besides that, the HAT is totally compatible with DFRobot Gravity Series which frees users from complicated connection work, and enables them to just concentrate on their projects building.

Raspberry Pi GPIO pins work with a maximum logic level of 3.3V. Besides the 3.3V power sensor and module, the product also supports:

• Sensor and module with 5V power supply and 3.3V level
• PWM external power supply (6~12V)
• Controlling multiple servos

Specification

• Driver Maincontroller: STM32
• Operating Voltage: 5V
• PWM External Power Supply: 6-12V
• PWM Pin Voltage: 5V
• Sensor Interface Power Supply: 3.3V
• Communication Interface: 28 digital Ports, 4 groups of analog port, 3 groups of IIC port, 1 group of UART, 4 groups of 5V power interfaces, 1 group of SPI, 1 group of IIS port
• Device Address: 0x10
• Outline Dimension: 65×56mm/2.56×2.20”

Board Overview

Note:

• The GPIO number in this board adopts BCM codes.
• When the VP port is not power by external power, the voltage of PWM ⊕ is 5V.
• When the VP port is powered by external power, the voltage of PWM ⊕ is equal to that of the VP external power (6-12V).
