The 3v3 pin on my TTGO v1.7.1 is measured as 3v854 on two multimeters. This voltage actually goes to the ESP32 chip, so I'm wondering two things:
Why is the voltage so high?
How does the ESP32 D0WDQ6 chip survive?
The voltage regulator on the board has a mark LPS A18A2 on top, which I can't find on the internet. According to the TTGO schematic this should be a SY8008B LDO.
Do I have a fake TTGO or is something else going on? Specifically, should I replace that voltage regulator (SOT223-5 format) with a known device that gives out 3v3?
The board is working just fine, with WiFi and ESP32-NOW all enabled, but I am wary about using this device "in the field".
