      Hi,
      I'm trying to set up a Gateway with the TTGO LoRa32 V2.1-1.6.1 board. But information on the product page is only about V1.6: -> http://www.lilygo.cn/claprod_view.aspx?TypeId=62&Id=1130&FId=t28:62:28

      • Are TTGO LoRa32 V2.1-1.6 and TTGO LoRa32 V2.1-1.6.1 are fully pin-compatible? What exactly is the difference?

      I want to use it as a single channel gateway -> https://github.com/things4u/ESP-1ch-Gateway
      Would this be the right config: (meaning right pin mapping):

      struct pins {
      	uint8_t dio0=26;		// GPIO26 / Dio0 used for one frequency and one SF
      	uint8_t dio1=33;		// GPIO33 / Used for CAD, may or not be shared with DIO0
      	uint8_t dio2=32;		// GPIO32 / Used for frequency hopping, don't care
      	uint8_t ss=18;			// GPIO18 / CS. Select pin connected to GPIO18
      	uint8_t rst=23;			// GPIO14 / D3. Reset pin not used	
      } pins;
      #define SCK 5
      #define MISO 19
      #define MOSI 27
      #define RST 23
      #define SS 18
      
      

      I also would like to use the OLED on the board, but am missing further infos:

      • what OLED exactly is mounted to the board? Which protocol is it using? Which pins are connected to it?

      Thank you in advance for your help.

            1. TTGO LoRa32 V2.1-1.6 is the same as TTGO LoRa32 V2.1-1.6.1, we just changed the silk screen on the board.
            2. The OLED on the board uses (SDA)21 , (SCL)22
            3. There are schematic diagrams and reference codes in our warehouse, please see here Link
