Read through this [Power supply for the ESP32 - #6 by Andreas - Stromversorgung / Power supply - Hiveeyes](https://community.hiveeyes.org/t/power-supply-for-the-esp32/1859/6)  
and what i experienced seems to be a very common problem with ESP32 boards for which the best solution seems to be the capacitor I added. Not sure why the vendors couldn’t address this with a tiny smd cap on the board but at least I can get the board to boot now.
