Take sensor monitoring, automation and control to the cloud using Particle Photon!*
This 4-Channel Relay Shield for Particle Photon makes it easy to control relays without sacrificing the use of your digital Input/Output lines. Send simple I2C commands to the integrated MCP23008 Digital I/O Port Expander to control the relays.
Four programmable digital I/O lines are also available for use in external digital logic applications. Integrated I2C expansion port makes it easy to add any of our I2C devices to your Particle Photon with a convenient plug interface. Dual Row headers give you wire access to your Particle Photon.
Plug in any of our expansion shields directly over the Particle Photon.
Powered by any +12VDC power source, this controller features an integrated switcher regulator that provides up to +5VDC at 500ma to power your Photon and just about any off-board circuit you may need. Our relay shields are simply the best available and very easy to use.
