Overview
Lcdbob is an open-source printed circuit board by orbcode, from the orbcode/orbtrace_hw repository on GitHub. It is a 2-layer board of 68.5 × 25 mm with 23 parts on 31 nets, routed with 312 tracks and 37 vias.
It is built around the B340. Its parts include 6 capacitors, 5 resistors, 5 connectors, 2 diodes and 1 IC.
Main components

README.mdORBTrace Hardware
This is the repository for various hardware for the ORBTrace project. There are various bits and pieces here but the most important ones are;
- ORBTrace Mini V1.0
- ORBMule demo board
- Breakout board for PMOD
You can also find the openSCAD source materials, and vinyl graphics, for the ORBTrace Mini V1 case.
These materials are provided in open form to learn from and improve on. We have deliberately chosen to not provide Gerbers for ORBTrace mini or STLs for the caseworks since your manufacturing processes are likely different to ours. Drop a note if you need those.

Questions
How big is the Lcdbob PCB?
It measures 68.5 × 25 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Lcdbob use?
23 parts, built around the B340. 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 Lcdbob KiCad files?
From the orbcode/orbtrace_hw repository on GitHub, at the commit this page was made from: the board is hw/lcdbob/lcdbob.kicad_pcb and its schematic hw/bob2/bob.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lcdbob design in my own project?
Its repository states no licence, so its author keeps all rights: ask orbcode before reusing the design.
