It is powered by a 400mAh rechargeable Lithium-Polymer battery.
The software includes <a href="https://github.com/technobly/Particle-NeoPixel">Particle-NeoPixel</a> for LED control, <a href="https://github.com/pololu/lsm303-arduino">lsm303-arduino</a> for e-Compass integration, and <a href="https://arduiniana.org/libraries/tinygpsplus/">TinyGPS++</a> for GPS parsing and distance/course calculations. <a href="https://docs.particle.io/tutorials/device-cloud/webhooks/">Webhooks</a> are used to communicate with the <a href="https://developers.google.com/maps/documentation/places/web-service/overview">Google Maps Places API</a>.
