The board I received ( https://github.com/looxis-renaud/ewinch_remote_controller/blob/main/doc/photo1665499714.jpeg ) looks slightly different than your's, which is probably the reason why I could not get the display to work. I did some tests and used a different display library than you, which seems to be a bit more up to date. Are you interested to test it and integrate it in your code via Pull Request?
I purchased the Paxcounter through the Aliexpress Link on this page: http://www.lilygo.cn/prod_view.aspx?TypeId=50060&Id=1271&FId=t3:50060:3
