Description
MCP23017 Based 32 Ch. Relay and Solenoid Driver with I2C Control
This is a 32 channel driver PCB intended to control relays and solenoids.
Control data is received from an I2C bus (requires a controller such as an Arduino).
Two on board MCP23017 16 bit GPIO expanders decode the data and control the loads via ULN2803 drivers.
