Why not use thread as shunt ? The power module use a 0.0005 shunt resitor for a mximum of 90 amperes. If we use the thread as shunt we can measure a current more than 90 amperes.
Example for 10 AWG wire with 10 cm long : The resistor for 10 AWG is ~ 3.27
I have tested the IMU only two weeks all the components works fine, and after I dont know why,
only IDG 500 doesnt response as you can see on arducopter configurator (blue and red graph). So I decide to remove the IDG 500 with my hot air solderin
