I tried 2 different power bank modules that did not work although I tested the output and it was steady 5v.
I also tried the mt3608 module and set the output voltage to 5.1v and still didn't work

10-15 minutes is more than enough run time on batteries.
I've tried about 5 types of step up converters none worked and I tried 18650 battery and lipo battery and those batteries for drones that have high current output (25C) and still wouldn't work.
I will try adding a couple capacitors and will see

I have a project that consists of an esp32 cam, esp32 wroom 32 pins, neo 6m gps module, hc sr04 ultrasonic sensor and max98357a i2s module. Everything works fine and as expected when plugged into a 5v adapter or directly into a PC or laptop however when I give the circuit 5v regulated voltage from a ...
