If an external power supply is required, simply connect the positive terminal of the external power supply to the 5V pin and the negative terminal to GND. (Supports 3.3–6V power supplies). Please note that when an external power supply is connected, the USB port cannot be used; you must choose between USB and external power.

Entering download mode: Hold down the BOOT button on the ESP32C3, then press the RESET button. Release the RESET button, then release the BOOT button; the ESP32C3 will now enter download mode. (You must re-enter download mode each time you connect. Occasionally, a single press may not suffice if the port connection is unstable and disconnects; you can determine this by listening for the port identification sound.)
