Description
ESP32-S2-Saola-1R is a small-sized ESP32-S2 based development board. 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-1R on a breadboard.
ESP32-S2-Saola-1R is equipped with the ESP32-S2-WROVER module, a powerful, generic Wi-Fi MCU module that has a rich set of peripherals. It is an ideal choice for a wide variety of application scenarios relating to Internet of Things (IoT), wearable electronics and smart home. The board a PCB antenna and features a 4 MB external SPI flash and an additional 2 MB SPI Pseudo static RAM (PSRAM).
