/**
* @ingroup boards_esp32_ttgo-t-beam
* @brief Board specific definitions for TTGO T-Beam board
* @{
*
* TTGO T-Beam is an ESP32 development board with 8 MB Flash that
* uses the EPS32 chip directly. It integrates a SemTech SX1276 or SX1278 for
* LoRaWAN communication in the 433 MHz or the 868/915 MHz band, respectively.
* Additionally, it has an OLED display connected via I2C on board.
*
* 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".
