ESP32-S2 Saola 1R Development Board

The ESP32-S2 is a highly-integrated, low-power, 2.4 GHz Wi-Fi System-on-Chip (SoC) solution that now has built-in native USB as well as some other interesting new technologies like Time of Flight distance measurements.

ESP32-S2 Saola-1 is a small-sized ESP32-S2 based development board produced by Espressif. Just about all of the I/O pins are broken out to the pin headers on both sides for easy interfacing. This particular Saola comes with a WROVER module, which has 4 MB Flash and 2 MB PSRAM.

Adafruit has CircuitPython for this board.  Espressif ESP32-S2 supports ESP-IDF master or version v4.2 and higher.
