From the project
Reverse Engineering of the 300zx (Z31) Digital Cluster & Design of replacement PCBs
Z31 digital clusters are one of, if not the best examples of this pure 1980s trend. Comprehensive instrumentation, large graphics, and gorgeous VFD illumination were a somewhat expensive option on the 300zx, as well as on Maxima, 240SX, Corvette, Celica/Supra, and a variety of other cars. As the cars languished in the transition period between "late model" and "classic", though, the digital package for the 300zx was not well liked.

DD Compute 1: common questions
What microcontroller does the DD Compute 1 use?
The DD Compute 1 is built around the Teensy3.6, from the NXP family.
How big is the DD Compute 1 PCB?
The DD Compute 1 measures 200 × 65 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the DD Compute 1?
167 components, from 41 distinct parts. The full bill of materials is listed on this page.
Where can I download the DD Compute 1 design files?
From the Acmex2564/Z31-DigiDash repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the DD Compute 1 design in my own project?
The repository has no license, so all rights stay with Acmex2564. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the DD Compute 1 without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug NXP firmware against it before you order a PCB.
