EasyMotor

This board is designed for in-flight characterization of research rocket motors. It records chamber pressure and acceleration to an on-board flash memory chip, the contents of which can be downloaded after flight over USB.
It can also be attached to a TeleMetrum or TeleMega using the companion interface to allow a subset of the data to be included in radio telemetry during the flight.

There is no EasyMotor firmware yet, but it will be part of the AltOS suite eventually.

Prototypes of v1 are underway. This design is not yet for sale.
