Display Considerations

Outer Area Width 268 mm Height 210 mm

Bottom Bezel 16 mm Notification LED area 10 mm Side Bezel 11 mm

Display Viewable Area Width 246 mm Height 185 mm

With modifications the bezel could support about... Width 256 mm Height 190 mm

Wisecoco 11 Inch AMOLED Width 231.64 mm Height 168.60 mm Too small

Surface Pro LCD 12 inch Width 254 mm Height 169 mm Good Candidate, maybe room for Camera?

Ipad Pro 11" Width 229.06 mm Height 159.99 mm A little small

Ipad Pro 12.9" Width 262 mm Height 196 mm This would be a great candidate but the interface is probably quite difficult https://www.panelook.com/LTL129JL01-A03_Samsung_12.9_Assembly_overview_31582.html

Questions

How big is the T61 LC Scanner PCB?

It measures 17.8 × 35.6 mm and has 2 copper layers, 1.6 mm thick.

What parts does the T61 LC Scanner use?

12 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the T61 LC Scanner KiCad files?

From the mukelarvin/thinkpad-x61-compute-module repository on GitHub, at the commit this page was made from: the board is USB_Laptop_Keyboard_Controller-master/TeensyLCT61/T61_LC_Scanner.kicad_pcb and its schematic CM4IO/CM4IOv5.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the T61 LC Scanner design in my own project?

Its repository states no licence, so its author keeps all rights: ask mukelarvin before reusing the design.
