ESP32-S2 Saola 1R Dev Kit featuring ESP32-S2 WROVER
The ESP32-S2 Saola-1 (WROVER) is a compact development board featuring the ESP32-S2 with 8MB Flash and 2MB PSRAM. It breaks out nearly all I/O pins for easy prototyping, includes CP210x USB-to-serial for programming, and offers a second USB port for native connectivity.
ESP32-S2 Saola-1 is a small-sized ESP32-S2 based development board produced by Espressif. Just about all 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 - we recommend two breadboards 'side-by-side' since the Saola is a bit wide, and you won't have extra holes on one side for wiring.
This particular Saola comes with a WROVER module, which has 8 MB of Flash and 2 MB (16 Mbit) PSRAM mounted for a roomy development environment!
One micro USB connector on the Saola is wired through a CP210x USB to serial converter chip for debugging and programming. The native USB is available on a second micro USB connector.
We do have CircuitPython support for this board! And Espressif provides Arduino IDE support too.
Espressif ESP32-S2 supports ESP-IDF version v4.2 and higher. You’ll find information to get started with ESP32-S2-Saola-1 board and hardware documentation (e.g. schematics) in Espressif’s Documentation website.
