Overview
TR108 Mainboard is an open-source printed circuit board by directive0, from the directive0/TR-108 repository on GitHub, published under the MIT licence. It is a 2-layer board of 69 × 98 mm with 22 parts on 59 nets, routed with 274 tracks and 64 vias.
Its parts include 11 connectors and 3 resistors. It belongs with the computers and single-board computers boards of this library.
README
README.mdThis repository hosts a set of design documents for the TR-108 Picorder. A Picorder is a Raspberry Pi based handheld device that records and displays sensor data for immediate analysis. The TR-108 is designed to use a Raspberry Pi Zero W, a set of custom designed PCBs, and a 3D printed enclosure to achieve this goal. This project, along with PicorderOS attempts to be a single self contained solution for anyone wishing to build their own Picorder.
What is included:
-
The design_docs folder contains a crude SVG file that shows the 2D layout of the original design, mostly to scale. The SVG includes a crude wiring diagram.
-
The pcb_design folder contains KiCad files of the proposed printed circuit board to replace the original perfboard prototype. These files can be used to produce and test PCBs.
-
The enclosure_design folder contains STLs (incomplete) and a .blend file containing the raw construction file for a complete enclosure, based closely on the DST Tricorder toy.
What is not yet included:
- There are no assembly instructions. I hope to produce some in the future.
While it is not required, if you make a picorder using this repository I would appreciate you sharing photos or videos your build with me at chris@squaredwave.com.

Questions
How big is the TR108 Mainboard PCB?
It measures 69 × 98 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TR108 Mainboard use?
22 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 TR108 Mainboard KiCad files?
From the directive0/TR-108 repository on GitHub, at the commit this page was made from: the board is pcb_design/TR108 Mainboard KiCadv7/TR108 Mainboard.kicad_pcb and its schematic pcb_design/TR108 Mainboard KiCadv7/TR108 Mainboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TR108 Mainboard design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
