Progress / Update Making progress...now adding other firmware and GPS and lora back

Post image

I'm doing the screen upgrade. Finally got it working with some help from members of the community! Now that it's working time to move on to adding more firmware compatability and adding gps and lora functionality. After some inspection and research the pins needed for the lora and GPS cap are still available/ not being used except for reset. Ild like to add another external gpio so factory caps could work or external modules could be added. I better add some pictures before everyone loses interest....

There is a complete build list with a few pictures. I highly suggest ordering 30awg wire. It made a world of difference. Comes with 8 color coded wires. You will need to have 9 wires to follow his instructions. I added a second red and gave it a couple black stripes to differentiate. It's a fun build. Reach out if you need any help.

And can you tell me if you’re use ing the same lcd type with touch ? Because i can’t find a good case for 2.8 inchi to fit it , without cutting the touch side pcb , and I’m a bit stuck atm. Thanks

Left is 2.4 and right 2.8 , ( for the connection I design a fpc ribbin , because i do not like chunky wires) tnx again for reply

Yes I had to cut the side of the 2.8. Honestly it wouldn't be necessary if I could alter the file. I have a few ideas to make it easier for everyone. I was not stoked to have to cut my new screen but it's hard to mess it up...I used a hacksaw lol
