ESP32C3 SuperMini Wont Run

[Barbeta]

Hi everyone,

I’m having some issues with an ESP32-C3 SuperMini. Sometimes, when I press the button, everything works fine, but other times the ESP just doesn’t start, out of about 10 attempts, it only works around 6 times.

I’m not sure if this is a wiring problem or if I’m missing something in the setup. I’ll attach the circuit diagram and the ESP pinout for reference.

Any help or suggestions would be greatly appreciated!

gpio9 is the boot button. If this is low during boot, the chip will be waiting for a firmware upload. You should not connect it to anything that may be active during boot (even something that may just be hanging onto some extra capacitance).
