TL;DR.

Output high to measure voltage in the same why as other heltec device forces the ESP32 to try to pump 3.3v into the base of Q3. Solution, use internal pullup and pulldown resistor

Fixes #3760

WORK IN PROGRESS

Progress so far:

• Hasn't caught fire yet.
• Battery measurements seems ok

TODO:

• Measure current, check voltages at relevant pins.
  • Not in a position to measure differences for a few days.
• take a better look at code
• CLA issues? credit to OP?
• check circuit for tracker v1.0 and add it if there is the same issue

As mentioned here... haven't been able to do anything with this. Have a chance to look at this again now.

Todo:

• add the original HELTEC_TRACKER to the #ifdef
• test ( I only have 1.1)
• measure
