|
|
* @brief 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
|
|
* ```
|
|
* 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 \ref esp32_peripherals "Common Peripherals".
|
|
*
|
|
* @note
|
|
* Most definitions can be overridden by an \ref esp32_application_specific_configurations
|
|
* "application-specific board configuration".
