If you use the Arduino IDE to program the ESP32, you might be interested in [Andreas Spiess’] latest video (see below). In it, he shows an example of using all three ESP32 UARTs from an Ardui… ...

However, the USB port doubles as a power port. To use it as such, you need a USB cable and a 5V power source. In the case of the Arduino Nano, a mini-B USB cable is required.

Given that the Arduino-ESP32 port is brand new, indeed it’s still in progress, there is a lot of work for the community to do in getting it up to speed.

Just a quick one to note: Arduino has updated its Integrated Development Environment (IDE) for programming its devices. It's now Arduino IDE 2.2.0. The new features include Board and Port ...
