{1} Must be wired externally! #1 Required (used by LMIC for LoRa).
DIO1 is connected to a separate pin on pcb, but is not connected to GPIO33. Not on-board wired to any GPIO. Must be manually wired. <<-- necessary for paxcounter
Solder a wire from pcb pin labeled "LORA_IRQ" to pin "GPIO33" (see TTGO V2.0 pinout).
{2} Is not wired, but not needed for LoRa. #2 Optional (used by LMIC for FSK but not for LoRa). <<-- NOT necessary for paxcounter
{3} The on-board LED is wired to SCL (used by display) therefore totally useless! Not on-board wired to any GPIO. When needed: must be manually wired.
#3 GPIO22 is already used for SCL therefore LED cannot be used without conflicting with I2C and display.
