Tested - Works
This is a prototype board to help me do some field testing. The intent is to place this device near an obstacle on a single track mountain bike trail and attach the accelerometer to the obstacle. Bikes that cross that obstacle will then be sensed and the time and date of the bike’s passing recorded on a microSD card.
Currently, this project uses the following Sparkfun breakout boards: DS3234 Real Time Clock, MMA8452 Accelerometer, MicroSD
The next rev should - hopefully - get rid of the breakout boards and provide a complete circuit.
If you are interested in more, my email is on the board silkscreen.
