About the Custom ergo keyboard PCB

Custom ergo keyboard is an open source AVR/Arduino PCB design by myk-src, published on GitHub. It is a 2-layer board measuring 135.9 × 82.9 mm, with 90 components from 6 distinct parts.

Its main chip is the Arduino_Pro_Micro, from the AVR/Arduino family. Other key parts include the TRRS. By type, the board carries 42 switches, 42 diodes, 4 ICs and 2 connectors.

It belongs with the keyboards designs in this gallery.

From the project

Designed a custom ergonomic split keyboard in addition to a programmed QMK firmware that can be flashed onto it.

Custom ergo keyboard: common questions

What microcontroller does the Custom ergo keyboard use?

The Custom ergo keyboard is built around the Arduino_Pro_Micro, from the AVR/Arduino family.

How big is the Custom ergo keyboard PCB?

The Custom ergo keyboard measures 135.9 × 82.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Custom ergo keyboard?

90 components, from 6 distinct parts. The full bill of materials is listed on this page.

Where can I download the Custom ergo keyboard design files?

From the myk-src/custom-ergo-keyboard repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Custom ergo keyboard design in my own project?

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

Can I test firmware for the Custom ergo keyboard 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.
