ESP32-S2-WROVER Module | Module integrating the ESP32-S2 chip that provides Wi-Fi connectivity, data processing power, and flexible data storage. |
4.3” LCD FPC Connector | (Reserved) Connect to a 4.3” LCD extension board using the FPC cable. |
ESP Prog Connector | (Reserved) Connection for Espressif’s download device (ESP-Prog) to flash ESP32-S2 system. |
JTAG Switch | Switch to ON to enable connection between ESP32-S2 and FT2232; JTAG debugging will then be possible using USB-UART/JTAG Port. See also JTAG Debugging. |
Breakout Header 2 | Some GPIO pins of the ESP32-S2-WROVER module are broken out to this header, see labels on the board. |
USB-to-UART/JTAG Bridge | FT2232 adapter board allowing for communication over USB port using UART/JTAG protocols. |
Camera Header | Mount a camera extension board here (e.g., ESP-LyraP-CAM). |
Extension Header | Mount the extension boards having such connectors here. |
Reset Button | Press this button to restart the system |
Boot Button | Holding down Boot and then pressing Reset initiates Firmware Download mode for downloading firmware through the serial port. |
USB-UART/JTAG Port | Communication interface (UART or JTAG) between a PC and the ESP32-S2 module. |
USB Power Port | Power supply for the board. |
Battery Port | Connect an external battery to the 2-pin battery connector. |
Power On LED | Turns on when the USB or an external power supply is connected to the board. |
Power Switch | Switch to ON to power the system. |
RGB Jumper | To have access to the RGB LED, place a jumper onto the pins. |
RGB LED | Programmable RGB LED and controlled by GPIO45. Before using it, you need to put RGB Jumper ON. |
Power Regulator | Regulator converts 5 V to 3.3 V. |
I2C FPC Connector | (Reserved) Connect to other I2C extension boards using the FPC cable. |
Breakout Header 1 | Some GPIO pins of the ESP32-S2-WROVER module are broken out to this header, see labels on the board. |
Touch FPC Connector | Connect the ESP-LyraP-TouchA extension board using the FPC cable. |
Touch Switch | In OFF position, GPIO1 to GPIO14 are used for connection to touch sensors; switch to ON if you want to use them for other purposes. |
3.2” LCD FPC connector | Connect a 3.2” LCD extension board (e.g., ESP-LyraP-LCD32) using the FPC cable. |
