Welcome to a new InTheMail, the series that will touch both your passion for electronics and your bank account at the same time. We have a selection of different items received in this mailbag, some of them will probably go out as Christmas gifts to friends, some I’ll keep for myself. Let’s start with this ESP32-S2 development board.
This is the official Espressif dev board and is called ESP32-S2-Saola. It comes in two variants With UFL connector installed so you can use an external antenna or without the UFL connector installed to use with built-in antenna. So the reason for getting this development board was to play with the USB host functionality of the ESP32-S2, I’m working on a project where I have this usb device that creates a virtual serial port over USB. I would love to have that device connected into something like this and create a bridge for that serial port on the local network.
