Use the Particle Electron / Photon to provide cloud connectivity to a world of expansion controllers using the PEI2C expansion.
The PEI2C provides a 5 Volt I2C expansion port, allowing your Particle Electron or Photon to connect to different I2C devices.
Connect sensors for light level monitoring, gas level detection, temperature, and humidity monitoring, as well as many types of motion, acceleration, and direction sensors.
Connect our entire array of relay controllers, digital I/O expanders, PWM controllers, and current monitoring devices to your next IoT application with a simple daisy-chain interface.
The PEI2C provides a +5V I2C communication port, making it one of the most important expansions available. The PEI2C allows you to expand into the world of hardware so you can focus on software. The PEI2C is compatible with our PKFR Key Fob overlay expansion, allowing Key Fob communications with the Particle Electron or Particle Photon.
