  • 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 — 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 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 connector breakout, Type C USB connector breakout or USB data cable and hand-wire D19/D20 to D+ and D- pads.

    We do have CircuitPython support for this board, 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.
