Detailed Description
Board definitions that are common for all ESP32 boards.
This file contains board configurations that are valid for all ESP32.
For detailed information about the configuration of ESP32 boards, see section Common Peripherals.

◆ ESP32_XTAL_FREQ
| #define ESP32_XTAL_FREQ (40) |
External clock crystal frequency (MHz)
Most boards use a 40MHz crystal, including all those based on Espressif's WROOM-32 and WROVER-32 modules. Those that don't, like the SparkFun ESP32 Thing (26MHz), must define ESP32_XTAL_FREQ appropriately in their board configuration.
An obvious side effect of a mismatch is that the UART won't sync and the development terminal will show garbage instead of log output.
