ESP32-S2-Saola-1 Development Board based on ESP32-S2 WROVER Espressif ESP32-S2-Saola-1R/ESP32-S2-Saola-1M FZ4546

Overview

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-WROVER

*ESP32-S2-WROVER-I

*ESP32-S2-WROOM

*ESP32-S2-WROOM-I

Descriptions:

1, ESP32-S2-WROVER

ESP32-S2-WROVER is a powerful, generic Wi-Fi MCU module that integrates ESP32-S2. It has a PCB antenna, a 4 MB external SPI flash and an additional 2 MB PSRAM.

2, 2X20Pin I/O Headers Connectors

All available GPIO pins (except for the SPI bus for flash and PSRAM) are broken out to the pin headers on the board. Users can program ESP32-S2 chip to enable multiple functions such as SPI, I2S, UART, I2C, touch sensors, PWM etc.

3, USB to UART Bridge

Single USB-UART bridge chip provides transfer rates up to 3 Mbps.

4, Boot Button

Download button. Holding down Boot and then pressing Reset initiates Firmware Download mode for downloading firmware through the serial port.

5, Micro-USB Port

USB interface. Power supply for the board as well as the communication interface between a computer and the ESP32-S2 chip.

6, RGB LED

Addressable RGB LED (WS2812), driven by GPIO18.

7, 3.3V Power On LED

Turns on when the USB power is connected to the board.

8, Power Supply (3 methods)

5V via Micro USB port (default)

5V and GND header pins

3V3 and GND header pins

Note: ESP32-S2 only supports ESP-IDF master or version v4.2 and higher.

Package included:
1 X ESP32-S2-Saola-1R
