Usage

The pin mapping table for this hardware (L&E LoRa Module V1) and ESP32 with UART2 (UART_ID=2) is as follows:

L&E LoRa V1	ESP32
RX	GPIO 17
TX	GPIO 16
5V	5V
GND	GND
R	GPIO 33
S	GPIO 32

Micropython class UART Reference

Ref: class UART

ESP32

	UART0	UART1	UART2
TX	1	10	17
RX	3	9	16

The ESP32 has three hardware UARTs: UART0, UART1 and UART2. They each have default GPIO assigned to them.

Ref: ESP32 UART 📗

ESP8266

	UART0	UART1
TX	1	2
RX	3	8

UART0 is bidirectional.
UART1 is on Pins 2 (TX) and 8 (RX) however Pin 8 is used to connect the flash chip, so UART1 is TX only.
