Logging Features

Warning, this is the default firmware configuration. This may change.

One second of logging data contains:

Timestamp

4 bytes -> Integer --> Unix time since epoch in seconds

IMU

1800 bytes -> Floats --> 9 axis x 4 bytes (G, deg/sec, uTesla) @ 50 Hz

GPS

13 bytes --> 1 Bool (GPS Fix flag), 3 Floats (latitude, longitude, altitude) @ 1Hz

Barometer

8 bytes --> Temperature (C), pressure (kPa) @ 1Hz

Power

8 bytes --> Voltage (V), Current (A) @ 1Hz

TOTAL = 1833 bytes / sec

• 1 hour of logging data = 6.29 MB
• 1 day of logging data = 151.03 MB
• 1 week of logging data = 1.03 GB
• 6 weeks = 6.19 GB

Arduino firmware will last approximately 10 hours on a single charge.
