About the Atreus 54percent PCB

Atreus 54percent is an open source NXP PCB design by wolffjj, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 277 × 110.8 mm, with 181 components from 8 distinct parts.

Its main chip is the Teensy2.0, from the NXP family. By type, the board carries 61 resistors, 60 diodes, 58 LEDs, 1 IC and 1 transistor.

It belongs with the keyboards designs in this gallery.

From the project

This is the repository for my Backlit, 58 key Atreus Keyboard

The repository is a little messy right now, but hopefully the files are in working condition. Since I did a horrible job documenting ald labelling all of my pads, please let me know if the kiCAD files aren't workinf correctly.

I'll be slowly adding things and cleaning this up. I'm also currently working on a revision that will remove the Teensy 2.0 and solder the controller directly to the board, but don't count on that for a while, as this is just a hobby project :)

Atreus 54percent: common questions

What microcontroller does the Atreus 54percent use?

The Atreus 54percent is built around the Teensy2.0, from the NXP family.

How big is the Atreus 54percent PCB?

The Atreus 54percent measures 277 × 110.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Atreus 54percent?

181 components, from 8 distinct parts. The full bill of materials is listed on this page.

Where can I download the Atreus 54percent design files?

From the wolffjj/Atreus_54percent repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Atreus 54percent design in my own project?

Yes, under the terms of its GPL-3.0 license, which wolffjj chose for the repository.

Can I test firmware for the Atreus 54percent 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.
