Control eight relays using this I2C relay controller.
Integrated port expander (MCP23008 from Microchip) controls eight relays through the I2C bus.
Add more relays, digital I/O, analog to digital converters, sensors, and other devices using the integrated I2C expansion port.
Operates on 12VDC using a 2.1mm barrel connector (center positive) or 2-wire terminal block.
This is a general purpose I²C device compatible with all computing platforms and IoT technologies, including Raspberry Pi, BeagleBone, Arduino, Particle, BridgeX5, and many more. All ControlEverything.com devices support a strict +5V I²C Bus standard.
