Description: ESP32-S2-Saola-1 is a small-sized ESP32-S2 based development board produced by Es-pressif. 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. ESP32-S2-WROVER Module: 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. Pin Headers: 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. 3.3 V Power On LED: Turns on when the USB power is connected to the board. USB-to-UART Bridge: Single USB-UART bridge chip provides transfer rates up to 3 Mbps. Reset Button: Reset button. Micro-USB Port: USB interface. Power supply for the board as well as the communication interface between a computer and the ESP32-S2 chip. Boot Button: Download button. Holding down Boot and then pressing Reset initiates Firmware Download mode for downloading firmware through the serial port. RGB LED: Addressable RGB LED (WS2812), driven by GPIO18. Specifications: ESP32-S2-WROVER modules with 4 MB Flash and 2 MB PSRAM USB – One 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. Misc – Boot and reset buttons, compatible with Neo Pixel RGB LED, 3.3V power on LED Power Supply (3 methods) 5V via Micro USB port (default) 5V and GND header pins 3V3 and GND header pins It is recommended to use the first option: Micro-USB Port. Package Includes: 1 X ESP32-S2-Saola-1R Development Board
