Schematic shows the following:
Pin 3 is Vext on v1.1 - HIGH enables LDO for Vext rail which goes to:
GPS UC6580: GPS V_DET(8), VDD_IO(7), DCDC_IN(21), pulls up RESETN(17), D_SEL(33) and BOOT_MODE(34) through 10kR
GPS LNA SW7125DE: VCC(4), pulls up SHDN(5) through 10kR
OLED: VDD, LEDA (through diode)

* Fix Heltec Tracker Screen issues
Fix Heltec Tracker Screen issues like wrong offsets, display size and screen not shutting down.
Divides board into two different envs for 1.0 and 1.1 version PCB
* Helteck wireless tracker default version V1_1
* rename heltec tracker 1.1 - trunk fmt
rename varian of heltec tracker 1.1 to "heltec tracker" to be retro-compatible.
Trunk formatting.
* Heltec Tracker increase Screen update to 3Hz
Heltec Tracker increase Screen update to 3Hz from 1Hz
* Add battery level with lookup table
now uses a lookup table to better calculate battery level of different cells
* LifePo4 and PB battery table - added voltage filter
removed delay from adc reading, added a software filter to smooth out voltage readings. In those applications battery would last hours to days, no sudden change should be expected so a less frequent voltage reading or a more aggressive filtering could be done.
Note: to speed up convergence i initiliazied the last value to the minimum voltage, there are other and better ways to init the filter.
Added LiFePO4 and PB open circuit volta battery tables,
* Fixed ADC_CTRL , Checks for valid ADC readings
line 230/386 For heltec v3 and heltec tracker a different approach was used with the ADC_CTRL pin, now is more uniform using the same code for the 3 boards.
line 236 Check if the raw reading we are getting is Valid or not, count only the valid readings. This could lead to a division by 0 (improbable) so that's why at line 258 there is a check for that.
* updated OCV values
updated value to not OCV but to very low current, almost the same anyway
* Added Alkaline/Nimh voltage curve
Added Alkaline/Nimh voltage curve for AA/AAA and similar cells
* updates variants for new capacity measurement
* trunk reformatting
* trunk fmt
* Add LTO chemistry
