Description

Control 24 Relays and 8 digital input/outputs with only two I2C pins from your Arduino Micro* using this expandable relay shield.

This controller provides an ideal host environment for your Nano with an I2C expansion port and triple-row headers, retaining wire access to your Nano port pins. The on-board +5V 500ma switcher regulator is capable of powering your Nano, several I2C expansion modules, and many off-board circuits. This controller uses a pair MCP23017 I2C port expanders from Microchip to control 24 Relays, expandable to control 128 Relays through the I2C expansion port. Operates on +12VDC using a 2.1mm barrel connector (center positive) or 2-wire terminal block.

*Arduino Micro not included.
