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:

- Description
|
|
* - 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.
|
|
* - I/O Connector
|
|
- 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.
|
|
* - USB to UART Bridge
|
|
- Single USB-UART bridge chip provides transfer rates up to 3 Mbps.
|
|
* - Boot Button
|
|
- Download button. Holding down Boot and then pressing Reset initiates Firmware Download mode for downloading firmware through the serial port.
