Current sense not working #55

While testing logging, I noticed that the ADC was maxed out. This was on the board that currently has a sense amplifier soldered on. Did not have time to check the output voltage of the amplifier, so not sure if this is hardware or firmware issue.

Well its not an ADC issue the input is really close to 3.3V

Need to try on the other board

touched up the connections on the amplifier and it works. I suspect current sensing was just never properly tested on this specific copy?
