I ruined the I2C connector on my APM 2.5 board (and the solder pads where it should connect to the board), And I still want to connect an external magnetometer.
Is it possible? are there any other pins I can solder wires to the external mag?
Here is a picture of the bottom of the APM2.5 board:
The I2C connector pins are down in the lower right hand corner of the APM2.5 picture. You should be able to solder onto those pins if you are careful.
