GPIO22 useless (see #3)
{1} Must be wired externally!
DIO1 is connected to a separate pin on pcb, but is not connected to GPIO33.
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.
{3} The on-board LED is wired to SCL (used by display) therefore totally useless!
#1 Required (used by LMIC for LoRa).
Not on-board wired to any GPIO. Must be manually wired. <<-- necessary for paxcounter
#2 Optional (used by LMIC for FSK but not for LoRa). <<-- NOT necessary for paxcounter
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.
