* @ingroup boards_esp32_olimex-esp32-evb
* @brief Board specific definitions for Olimex ESP32-EVB (ESP32-GATEWAY)
*
* This configuration is for the Olimex ESP32-EVB, but can also be used
* for the Olimex ESP32-GATEWAY. To use this board definition with Olimex
* ESP32-GATEWAY, add
* ```
* USEMODULE += olimex_esp32_gateway
* ```
* 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".
