Preview: cheap APM Power Module for Cleanflight

How to measure gyro noise frequency with Blackbox
Betaflight (and INAV) lowpass filter tuning can be a hard thing to do if you have not idea what is noise frequency you want to cancel. Sure, you can blind test or read tutorials. But what if I tell you, you can measure it quite precisely using only Blackbox logs? Or measure rotation speed of…
