    Great little ESP32 board. And as other reviewers noted: check the battery cable polarity, mine was reversed polarity compared to Pololu/Adafruit JST-battery cables.

    Very good quality board. The reverse battery polarity problem has been fixed. This board has exactly same pin out of Adafruit HUZZAH32 – ESP32 Feather Board. In my opinion its better than other esp32 boards coz it has a voltage divider connected to analog pin 13 by which u can monitor battery voltage. No need to add external resistors. And it also has a disable pin for the onboard voltage regulator by which u can save power when in deep sleep mode. Visit the adafruit page for more details.

    I bought two TTGO ESP32 modules. They look very solid unlike some other TTGO variants. The board is very well designed for usage with a battery. In normal mode the board takes about 40mA. When you power with battery and go into deep sleep then consumption goes down to 130µA. The board also allows to switch off the power regulator which reduces the consumption to 70µA on battery in deep sleep. This should allow to power the board for a very long time on a single charge.
