p.s. anyway i bet that the problem could be inside the wifi connection, because if i use usb cable to power on ESP32 (5v and gnd disconnected) i wait 15-20seconds (wifi in this time will connect) then connect 5v and GND, and after that wait 5seconds and disconnect usb cable. in ...
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) ...
Cable quality - obviously very important - as is the adapter itself - esp with devices where the power in is also a USB-OTG - a bad power supply there can be a bag of hurt even more... Keep in mind that it's supplying volts/amps to a PMIC on the Tinker... on a non-PMIC dev...
First off, we're going to wire the 5V output to the +5V rail, with a diode. The Raspberry Pi HAT is setup in a breadboard format, which makes everything easy to wire. Connect the diode to the last pin of the PowerBoost header, and the other pin to a hole on the +5V rail. Tr...

Powering VDD3P3_RTC with 3.3V 30mA always on LDOby R-8020 » Sun Mar 12, 2023 6:49 am Is it possible to power RTC from a 3.3V 30mA always on output from LDO to keep RTC running while chip is off? I know the pin supplies VDD_SPI and i'm using that to power flash and ...
I have a few TTGO boards with a switch on them and the battery charge. It seems however that if you plug in USB , the esp32 comes in regardless of the switch position, so to charge the battery the esp32 has to be on. To me this seems pointless and a bad design, who wants the...
