What are the default UART0 RX/TX pins for the ESP32S2?
As shown in the ESP32S2 datasheet:
U0TXD(UART 0 transmit) isGPIO43, which is pin 48 in the QFN56 package#U0RXDisGPIO44, which is pin 49 in the QFN56 package
As shown in the ESP32S2 datasheet:
U0TXD (UART 0 transmit) is GPIO43, which is pin 48 in the QFN56 package#U0RXD is GPIO44, which is pin 49 in the QFN56 package
