Is, SDA and SCL accurate? How is the OLED connected? How is the LORA sx1276 connected? If the OLED is not using 21,22 I would recommend you add additional defines

// OLed
static const uint8_t OLED_SCL = 15;
static const uint8_t OLED_SDA = 4;
static const uint8_t OLED_RST = 16;

// LoRA
static const uint8_t LORA_SCK = 5;
static const uint8_t LORA_MOSI = 27;
static const uint8_t LORA_MISO = 19;
static const uint8_t LORA_CS = 18;
static const uint8_t LORA_RST = 14;
static const uint8_t LORA_IRQ = 26;

It think it would be useful.
Chuck.

And we have LED and button on board:

// LED (attn: is active low!)
static const uint8_t LED_BUILTIN = 2;

// button ("PRG")
static const uint8_t BUTTON = 0;

@stickbreaker The Version 1 boards use pins 4,15,16 for OLED so makes more sense to get these definitions into pins_arduino.h along with the LoRa radio defs. I had these in my example programs at CaptIgmu/Arduino/tree/master/esp32/TTGO_LoRa32_OLED. Thank you Chuck, I will add some commits!

@cyberman54 These are defined in pins_arduino.h

static const uint8_t LED_BUILTIN = 2;
#define BUILTIN_LED  LED_BUILTIN // backward compatibility

static const uint8_t KEY_BUILTIN = 0;

I don't need the PRG button in my applications but you could re-assign the constant in your program! Thanks.
