# Wheel Counter, Battery Powered, RFM69 at 433MHz

## Objective
- Monitor how much critters are running on their wheels, at [The Creature Conservancy](http://www.thecreatureconservancy.org/).  Physical activity could correlate with health
- Create a wireless, battery powered, sensing network for additional sensors in the future

## Features
- NFC antenna for quick reading/changing of metadata (i.e. setting the animal name for transmission)
- RTC (Real Time Clock)
- N-MOSFET polarity protection
- Several debug switches
- TagConnect interface
