Heltec wireless tracker

I am trying to connect to TTN with the Heltec wireless tracker, but I cant find all the DIO pins.
I found DIO1 on pin 14, but I need DIO0 to.
Can somebody pass me the information to the right place to look.

Maybe provide a link to the product so we know we’re looking at the correct hardware?

This is the link to the product

And what software do you want to use?

I am now using this pio init file:
; PlatformIO Project Configuration File
;   Build options: build flags, source filter
;   Upload options: custom upload port, speed and extra flags
;   Library options: dependencies, extra library storages
;   Advanced options: extra scripting
; Please visit documentation for the other options and examples
; https://docs.platformio.org/page/projectconf.html

platform = espressif32
board = heltec_wireless_tracker
framework = arduino
monitor_speed = 115200

lib_deps =
  # Accept new functionality in a backwards compatible manner and patches
  MCCI LoRaWAN LMIC library

build_flags = 
  -D hal_init=LMICHAL_init
  -D CFG_eu868=1
  -D CFG_sx1276_radio=1

There is no DIO0 on that board.

And there is no driver for the SX1262 in LMIC.

So you could use the tracker code provided by Heltec.

Or change boards …

Looking at the specs of the board you linked to that isn’t right. This definition is for older Heltec hardware. Use the Heltec provided software for that board.

Thanks you both, I see the problem now.
I dive into the Heltec software.
Thanks again. This was very helpfull

Update diving:
Got the wireless tracker working on TTN with this library: GitHub - ngraziano/LMICPP-Arduino: Lmic (LoraWAN-in-C) modified to C++
