See the following two models for v2.1 compatibility
Refer to this discussion to determine which one suits your needs best.
This work is based on sttts's Waveshare 5.5inch mount. BTT PITFT50 v2 has a different layout than v1, featuing a brightless thumbwheel, an orientation switch and a JST XH port for unknown function. This design provide accessibility to the thumbwheel and switch.
Please use the mount in sttts's mods to amount this to the frame. No re-print of skirts is required!
