It belongs with the keyboards designs in this gallery.

From the project

Building a 4x4 macro keyboard using left-over Cherry MX Red key switches and left-over keycaps. Will use AT90USB1286 microcontroller, since the typical ATMega microcontroller is unavailable.

Bakeneko-60: common questions

What microcontroller does the Bakeneko-60 use?

The Bakeneko-60 is built around the C44854, from the AVR/Arduino family.

How big is the Bakeneko-60 PCB?

The Bakeneko-60 measures 284.7 × 94.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Bakeneko-60?

153 components, from 22 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Bakeneko-60 design files?

From the hsaito18/mini-keyboard repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Bakeneko-60 design in my own project?

The repository has no license, so all rights stay with hsaito18. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Bakeneko-60 without the hardware?

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