ESP32 Forum

Hi!

I've got a question on the ESP32-PROG power selector jumpers. I want to power my own board trough the USB connection of the ESP32-PROG. My board has 5v and 3v3 components, so I want the jumpers to select 5v. Does doing so also alter the RX/TX & JTAG signals to 5v since the ESP32 is not 5v tolerant?
Thanks!

Power on ESP-PROG could be toggled between 3v3 and 5v, but the signals will always be 3.3 V level.
