Using µC as FTDI to upload program?

[zackdvd]

Hi,
I do not own a FTDI to upload my program to (in my case) an ESP32-CAM.
I wonder if I can use a ESP32 or Raspberry Pi pico for that job?
So upload the right program to them and use them as a programmer?

I found that for the pico, is it possible to get that project into an Arduino project?

GitHub - Noltari/pico-uart-bridge: Raspberry Pi Pico UART-USB bridge

Hope to find some of you you are willing to discuss this question here. Hope it's in the right place, was not easy to pick the right spot...

Thank you!

Thank you for that, good information!

I'm not familiar with the ESP32-CAM, but be very careful using 5V devices (like the Uno) on a 3.3V device.

You may get away with it, but you may not. Some 3.3v devices (like the ESP32) are not tolerant of a 5v (like the Uno) logic level.
