Re: ESP32-S3-DevkitC does not boot up when powered by external 5V supply

I corrected my original post.
My last post says:
"I added a 10uF capacitor between RST(EN) and GND"

Correction to last post. I added a 10uF capacitor between RST(EN) and GND.

Re: ESP32-S3-DevkitC does not boot up when powered by external 5V supply

I added a 10uF capacitor between 5V and GND. It still did not boot up and run the program the first three times I applied 5V. However, it did start up the forth time I applied 5V. So this is solution looks like movement in the right direction but marginal and that obviously is not good enough. Any o...

Re: ESP32-S3-DevkitC does not boot up when powered by external 5V supply

OK. I will try that. Just to clarify, it looks like the EN pin is connected to the RST pin on the Devkit board (pin 3 on J1). Is this correct?

When I remove the USB connection and power the DevkitC board with an external 5V DC power supply, the program does not run. If I press the reset button the program runs. How ca...
