Hello 
I am using two ESP32C3 and both only run the programm when I connect them to my PC. When I use the 3,3V Input via a normal power supply the program does not start. And when I’ve disconnected the board for a long time it is not enough to only connect it again. I have to upload the same code again to make it run. Both boards show this behavior. Any advice?
Try using one of these boards to connect to power
Ensure that the power supply you are using provides a stable and sufficient 3.3V output. Unstable power supply or voltage drops could cause the ESP32C3 to malfunction or fail to start properly.
- Double-check the power supply’s voltage output using a multimeter to ensure it consistently provides 3.3V.
- Consider using a different power supply with higher current capacity (mA) to ensure it can handle the power demands of the ESP32C3.
I just realized the XIAO Expansion board can power the SAMD via the 5v pin, but the ESP32 Xiao does not accept power this way, so the expansion board is useless to power this processor, and the current expansion board does not have bottom pins to energize the esp32 Errr… what da?
