TMA, short for Telemetrics A is a physically tiny PCB design to put into model crafts such as model rockets. You can power it through a LiPo cell, it will start recording data from an Inertial Measurement Unit and Barometric Pressure Sensor as soon as the board receives power and the collection jumper is set.

The diameter of this board is 18mm.

Values are stored in flash memory overwriting the same sector of flash continually when there is too much data.

Powering on the board without the collection jumper being set allows you to speak I2C to the board to get the data out of the flash memory again.
