Thing Plus - Wroom esp32 Powered by regulated 3.3v on 3.3v Pin

Hi

If i was to power the board externally on the 3.3v pin using a regulated power supply of 3.3v, would i still be able to use the usb to connect to a pc for uploading firmware?

I plan on updating the firmware by OTA Wifi but i would like to know if i can achieve both options?

thanks in advance

Nick

Thanks for reaching out to us on this.

Yes, if using the 3.3v pin (not the v+bat pin) - please reference our hookup guide, as this and many other helpful features are covered https://learn.sparkfun.com/tutorials/es … 1615791300 (scroll ~4/10 the way down to the section covering power)

Hope this helps, and happy sparking!
