  • 16 I2C Controlled Relays
  • MCP23017 I2C Port Expander
  • Sale
  • Regular price $158.95

Description

On-board LEDs indicate the status of each relay. This 16-channel relay shield uses the popular MCP23017 I2C port-expander for relay control, using only 2 pins of your Arduino Micro for I2C communications. Set or read the status of each relay using our sample Nano firmware. Integrated I2C output gives you plenty of expansion options using any of our I2C expansion devices. Monitor sensors and control relays using our code samples and write complex applications in a few hours instead of a few days. Integrated +5V 500ma switcher regulator powers your Nano and all your I2C expansion devices with ease. Operates on 12VDC using a 2.1mm barrel connector (center positive) or 2-wire terminal block.

*Arduino Micro not included.
