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. Developers can either connect peripherals with jumper wires or mount ESP32-S2 Saola-1 on a breadboard - Adafruit 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.

## Description

**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. Developers can either connect peripherals with jumper wires or mount ESP32-S2 Saola-1 on a breadboard - Adafruit 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 2 MB (8 Mbit) PSRAM mounted for a roomy development environment!

The micro USB connector on the Saola is wired through a CP210x USB to serial converter chip for debugging and programming. The native USB is *not* available on a USB connector - instead you'll want to pick up a [Micro B USB](https://core-electronics.com.au/usb-micro-b-breakout-board.html) connector breakout, [Type C USB](https://core-electronics.com.au/adafruit-usb-c-breakout-board-downstream-connection.html) connector breakout or [USB data cable](https://core-electronics.com.au/usb-type-a-plug-breakout-cable-with-premium-female-jumpers-30cm-long.html) and hand-wire D19/D20 to D+ and D- pads.

[We do have CircuitPython support for this board](https://circuitpython.org/board/espressif_saola_1_wrover/), but as mentioned above, you will have to wire up the USB connectivity to access the CircuitPython disk drive and serial port.

Espressif ESP32-S2 supports ESP-IDF master or 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](https://docs.espressif.com/projects/esp-idf/en/latest/esp32s2/hw-reference/esp32s2/user-guide-saola-1-v1.2.html#).

**Specifications:**

- ESP32-S2-WROVER modules with 4 MB Flash and 2 MB PSRAM
- USB – 1x Micro USB port for power and programming / debugging via USB-to-UART bridge
- Expansion – 2x 20-pin I/O headers with SPI, I2S, UART, I2C, touch sensors, PWM, etc…
