About the Kowgary16 cfx PCB

Kowgary16 cfx is an open source AVR/Arduino PCB design by ChrisChrisLoLo, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 68 × 69.4 mm, with 51 components from 15 distinct parts.

Its main chip is the ATmega32U4-M, from the AVR/Arduino family. By type, the board carries 17 switches, 16 diodes, 7 capacitors, 6 resistors, 1 IC and 1 crystal.

It belongs with the keyboards designs in this gallery.

From the project

A 4x10 CFX spaced low-profile mechanical keyboard.

A 4x10 CFX spaced low-profile mechanical keyboard.

Uncompromisingly small. Unabashedly uwu.

Also contains the source code for the 4x12 minipeg48 and the 4x4 kowgary16.

This keyboard also has the design files needed to order your own accompanying 3D-printed/Aluminum CNC case!

Additionally, you should need - 40 (plus spare) kailh choc switches. Avoid Red/White/Brown switches as they can be pretty rattly. Pro Red/Silver/Sunset switches are good places to start. - 40 (plus spare) 1u CFX keycaps

Kowgary16 cfx: common questions

What microcontroller does the Kowgary16 cfx use?

The Kowgary16 cfx is built around the ATmega32U4-M, from the AVR/Arduino family.

How big is the Kowgary16 cfx PCB?

The Kowgary16 cfx measures 68 × 69.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Kowgary16 cfx?

51 components, from 15 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 Kowgary16 cfx design files?

From the ChrisChrisLoLo/bancouver40 repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Kowgary16 cfx design in my own project?

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

Can I test firmware for the Kowgary16 cfx 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.
