Barometer

Magnetometer

The board has a built in magnetometer using the HMC5883 chip.

Magnetometer Conflict M8N GPS with Compass

[1]

When using a M8N GPS with built in external HMC5883 magnetometer, the external HCM5883 will not work due to conflicts with built in SP Racing F3 internal HMC5883 chip. The solution would be to desolder, or cut the traces, to the SP Racing F3 internal HMC5883 chip.

Otherwise, specify the external MAG by cli command mag_hardware. The value differs from firmware to firmware, e.g.:

CleanFlight (and probably BetaFlight): https://github.com/cleanflight/cleanflight/blob/master/docs/Cli.md

iNav: https://github.com/iNavFlight/inav/blob/master/docs/Cli.md

There is a repeated discussion on iNav thread on this subject. https://www.rcgroups.com/forums/showpost.php?p=35357776&postcount=7411

Clones

Issues

Some clones have a buzzer design flaw where the buzzer connector negative is connected to the main ground plane of the board causing the buzzer to buzz constantly. The fix is to use the buzzer pads on the underside of the board instead.
