The Adafruit I2C to 8-Channel Solenoid Driver module enables easy control of up to 8 solenoid actuators via the I2C bus. It features an MCP23017 GPIO expander and supports supply voltages from 3 V to 24 V. Each solenoid channel is driven by an AO3406 MOSFET and protected with a flyback diode. Since the expander provides 16 GPIO pins, the module also offers Port B with eight general-purpose pins for additional use.
The board includes three jumpers (A0–A2) for setting one of eight I2C addresses, allowing the system to be expanded to control up to 64 solenoids. Communication is handled through STEMMA QT / Qwiic connectors for easy, solder-free connection. The driver can be powered and controlled with either 3 V or 5 V logic, making it compatible with both Arduino and Raspberry Pi.
