This is just a feature that might be of interest to Arduino/ESP32 etc developers.
I became stuck needing to program an ESP32Cam without having an FTDI.
So, this showed me how to do that - I suppose that this will work when programming via the B4R IDE - since one would be writing to the ESP32Cam via an UNO. Haven't tried it. Just making a supposition.

Look for this heading down the page : How to Upload the code to ESP32-CAM using Arduino UNO
I guess that should work with other devices without USB etc. as a pass-through from IDE via UNO to relevant device.
