Changes in hardware: - MAX17048 for battery monitoring instead of ESP32 ADC - Onboard LiPo protection for overvoltage, undervoltage and overcurrent (DW01A) (issue #53) - Testpoints added for critical signals - Capacitor on ESP32_EN changed from 100nF to 1uF ( issue #62) - Easier to source LiPo charger (TP4056) - LiPo charger status input fixed(issue #55) Changes in software: - MAX17048G added as source for battery stats (enabled by defining board revision 4 in Platformio.ini)
