The Nano V1 is a tiny, lightweight barometric altimeter and flight data logger. Below are the specifications across hardware revisions. Revision 4 and later boards add an inertial measurement unit (IMU) and an upgraded pressure sensor — the hardware revision is printed on the back of the PCB. You can also identify your revision over the USB connection.
Time, altitude, velocity, air pressure and temperature. Rev 4+ also logs tilt, pitch, roll, yaw, acceleration (magnitude and per-axis) and gyroscope (per-axis).
