Follow the advice below for best performance and long-life of your flight controller:
Apply resin/glue to reinforce JST-SH connectors - helps if you crash your aircraft.
Using an enclosure/box for the flight-controller is recommended.
Install open-cell foam under the pressure sensor - sandwich some between the FC and frame.
Route motor/battery wires as far away from the compass sensor (magnetometer) as possible.
Only install the BOOT jumper pins if you need them.
Using color coded pin headers is recommended (not supplied), especially for VBAT headers.
Do everything you can to prevent vibrations reaching the accelerometer/gyro sensor.
