Board specific definitions for Espressif ESP-WROVER-KIT V3.

The Espressif ESP-WROVER-KIT is a development board that uses the ESP32-WROVER module which includes a built-in 4 MByte SPI RAM. Most important features of the board are

  • Micro-SD card interface
  • OV7670 camera interface
  • 3.2” SPI LCD panel
  • RGB LED

Furthermore, many GPIOs are broken out for extension. The USB bridge based on FDI FT2232HL provides a JTAG interface for debugging through the USB interface.

When the camera module is connected, add 

1
USEMODULE += esp32_wrover_kit_camera
to the makefile of the application to use the according default board configuration.

For detailed information about the configuration of ESP32 boards, see section .
