Carloop Basic is the most basic starter kit to access data from your car. Comes with a Particle Photon and no additional cables required. The Photon gets its power from Carloop when connected to the OBD-II port. Since the Particle Photon is a microcontroller with a WiFi radio, it makes for a great trigger for IFTTT and any Smart Home devices! Find example apps at community.carloop.io
Carloop is also available in a 3G cellular option.
