GPIO33 DIO1 (see #1)

GPIO32 DIO2 (see #2)
|

GPIO22 SCL SCL
|

GPIO21 SDA SDA
|
|
|
|
|
GPIO22 useless (see #3)
|
|
|
|
|
|
|
|
|
|
#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.
