Gyro Logger user Manual

• Input Voltage: 2 - 6S
• IMU type: BMI270
• Max log frequency: 1.2kHz
• Log type: Betaflight Log
• optional external trigger: momentary switch, PWM
• LED indicator: RGB LED

New versions of our logger (start 05.2023) utilize a custom Betaflight Firmware to display the current BlackBox status. The following colors are used for each BlackBox State if you choose ARM State as LED function (default config):

• Running is green but can be changed via Betaflight Config
• Disabled, Stopped, Paused, Shutting Down is red but can be changed via Betaflight Config*
• Prepare Log File, Cache Flush, Start erase is blue and can't be changed
• Send Sysinfo, Field, GPS and Slow Headers is yellow and can't be changed
• Erasing and Start Erasing is orange and chan't be changed

*To change these colors head to the Betaflight LED Config and set the colors you want under ARM State called “Armed” and “Disarmed”.

1. Power on the logger/drone/camera
2. After powerup, the logger must initialize. This takes roughly 2 seconds of time during which is has to be steady (similar as with the drone flight controller powerup)
3. After the initialization the logging automatically starts
4. After landing, turn of the logger by flipping the switch
5. Remove the SD card and transfer the logs to your computer
6. Import the Video, Lens profile and Log file into Gyroflow
7. Select the correct gyro orientation
8. Estimate gyro offset by comparing liftoff time in Log and Video (Blackbox explorer helps!)
9. Press auto sync and the video and log file should be synced
