This is a top case for the TD-1 to allow for the use of the 1.3" SH1107 OLED. This does require you to be a project supporter on my Patreon to access firmware v1.0.3 that makes this screen work. This can be used with self-sourced, and TD-1 kits.
More information on TD-1 can be found on my Patreon and my website.
The author marked this model as their own original creation.
