About the Mikeneko-65 PCB

Mikeneko-65 is an open source AVR/Arduino PCB design by takishim, published on GitHub under the MIT license. It is a 2-layer board measuring 303.8 × 94.2 mm, with 152 components from 21 distinct parts.

Its main chip is the ATMEGA32U4-MUR, from the AVR/Arduino family. Other key parts include the SRV05-4. By type, the board carries 67 diodes, 7 capacitors, 4 resistors, 2 ICs, 2 connectors and 1 crystal.

It belongs with the keyboards designs in this gallery.

From the project

Mikeneko65 is a 65% custom mechanical keyboard forked from Bakeneko65 (v3).

A simple 65% keyboard for DIYers. This project was forked from kkatano's Bakeneko65.

- Changed switch type from soldering to hotswap socket - Supported for PCB screw-ins stabilizer - Changed MCU to ATmega32U4-MU(R) to deal with MCU supply shortage - Added pcb/case/sockeet/switch foam

- Single piece tray case - O-ring gasket mount (Friction fit) - Uses Unified Daughterboard and Simplified Daughterboard as daughterboard - Supports QMK firmware, VIA, Remap and Vial - PCB designed with KiCAD 5.1.12

Mikeneko-65: common questions

What microcontroller does the Mikeneko-65 use?

The Mikeneko-65 is built around the ATMEGA32U4-MUR, from the AVR/Arduino family.

How big is the Mikeneko-65 PCB?

The Mikeneko-65 measures 303.8 × 94.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mikeneko-65?

152 components, from 21 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 Mikeneko-65 design files?

From the takishim/mikeneko65 repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Mikeneko-65 design in my own project?

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

Can I test firmware for the Mikeneko-65 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.
