New Espressif’s ESP development boards received, ESP32-S2, ESP32 aand ESP8266.

Just received ESP development boards from Espressif, ESP32-S2-Saola-1, ESP32-DevKitC V4, and ESP8266-DevKitC.

ESP32-S2-Saola-1 v1.2

ESP32-S2-Saola-1 is a small-sized ESP32-S2 based development board produced by Espressif. Most of the I/O pins are broken out to the pin headers on both sides for easy interfacing. Developers can either connect peripherals with jumper wires or mount ESP32-S2-Saola-1 on a breadboard.

To cover a wide range of users’ needs, ESP32-S2-Saola-1 supports:

  • ESP32-S2-WROOM
  • ESP32-S2-WROOM-I

The full model name of my board is ESP32-S2-Saola-1R, with chip embedded ESP32-S2-WROVER comes with a PCB antenna, 4 MB flash and 2 MB PSRAM.
