When the ESP32 came to the market, it was well equipped: Wi-Fi, Bluetooth, two fast cores, an ultra low power core, lots of pins, etc. One thing, however, was lacking: Native USB support like the SAMD processors, for example. This changed with the new ESP32, the ESP32-S2. Here I have two development boards. Let’s look if it is the same “killer” as the first ESP32 was.
