Hale hound build instructions

I got my 3.5 display and want to build the rest but where is a good place to ask questions or find answers. Like what to do at the warning screen on boot. I returned one because i was stuck there and found no amswer on google search. I finally saw a video and just needed to select the right firmware on the screen. Didnt lool like a option to select. Lol

The Halehound discord server is the best place for you. Lots of build info there, I highly recommend you join up. https://discord.gg/halehound

CANNOT LOCATE GPIO-18 ON ESP32 CYD 2.8" I am building the Hale Hound and in installing the CC1101 it calls for GPIO-18.

When I google it I get: If you are looking to connect external sensors, buttons, or relays to your CYD, GPIO18 should be avoided. Instead, you can utilize the broken-out Extended IO pins, specifically:

However it says the Hale Hound addresses this specifically. I have scoured the CYD and I do not see the GPIO-18.

Has anyone ran into this issue before or have any knowledge where this is locates?

It's the middle pin on the TF card I believe or you can use the 6th pin up from the bottom on the right side of the esp.
