=== Library ===

The ESP32 has three hardware UARTs: UART0, UART1 and UART2. They each have default GPIO assigned to them, however depending on your ESP32 variant and board, these pins may conflict with embedded flash, onboard PSRAM or peripherals.

Any GPIO can be used for hardware UARTs using the GPIO matrix, so to avoid conflicts simply provide tx and rx pins when constructing. The default pins listed below.

^ ^UART0^UART1^UART2|
|tx|1|10|17|
|rx|3|9|16|
