About the TR-108 PCB

TR-108 is an open source Raspberry Pi PCB design by directive0, published on GitHub under the MIT license. It is a 2-layer board measuring 69 × 98 mm, with 17 components from 12 distinct parts.

Its main chip is the Raspberry Pi Zero, from the Raspberry Pi family. By type, the board carries 11 connectors, 3 jumpers and 3 resistors.

Design files for the TR-108 Picorder

- 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.

TR-108: common questions

What microcontroller does the TR-108 use?

The TR-108 is built around the Raspberry Pi Zero, from the Raspberry Pi family.

How big is the TR-108 PCB?

The TR-108 measures 69 × 98 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the TR-108?

17 components, from 12 distinct parts. The full bill of materials is listed on this page.

Where can I download the TR-108 design files?

From the directive0/TR-108 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the TR-108 design in my own project?

Yes, under the terms of its MIT license, which directive0 chose for the repository.

Can I test firmware for the TR-108 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Raspberry Pi firmware against it before you order a PCB.
