I'm building commercial project based on esp32. It uses ESP-wroom-32 module, instrumentation amplifier and one mosfet. ESP32 is in BT mode. It is used in motorcycle so I would like to power it from ignition coils 14.8V. But how? I've tried using AMS1117-3.3, but that overheats and...
Re: Powering ESP32 WROOM Dev Boardby ESP_Sprite » Thu Jan 11, 2024 1:56 am It depends on the devboard in question, but for 95% of the boards out there, there's no issue. They tend to have a Schotty-diode from USB 5V to the general 5V line (e.g. D3 on the DevkitC) ...
after that i connect all my esp8266 using 5,5V and only one yellow pin esp32, and this time the esp32not boot. i measuere the voltage at esp32 vin-gnd pin and i measure 4,8v (not enought if we consider the test did before...) and much less than what i espected! (here myb...
