About the Torn Keyboard - Left PCB

Torn Keyboard - Left is an open source AVR/Arduino PCB design by EanNewton, published on GitHub under the MIT license. It is a 2-layer board measuring 140.8 × 115.7 mm, with 68 components from 21 distinct parts.

Its main chip is the ATMEGA328-PU, from the AVR/Arduino family. By type, the board carries 24 diodes, 22 switches, 8 resistors, 5 capacitors, 1 IC and 1 crystal.

It belongs with the keyboards designs in this gallery.

From the project

A collection of keyboards & things.

The split keyboard kit made with through hole components. The design has been inspired by the Corne, Plaid and Discipline keyboards.

Torn uses an Atmega328P cpu, running QMK with VUSB: - QMK firmware. - Bootloader. - Compatible with VIA

Later this year you will be able to buy a Torn keyboard kit from splitkb.com. Alternatively you can also buy all the parts needed youself.

Torn Keyboard - Left: common questions

What microcontroller does the Torn Keyboard - Left use?

The Torn Keyboard - Left is built around the ATMEGA328-PU, from the AVR/Arduino family.

How big is the Torn Keyboard - Left PCB?

The Torn Keyboard - Left measures 140.8 × 115.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Torn Keyboard - Left?

68 components, from 21 distinct parts. The full bill of materials is listed on this page.

Where can I download the Torn Keyboard - Left design files?

From the EanNewton/Awesome-Keebs repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Torn Keyboard - Left design in my own project?

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

Can I test firmware for the Torn Keyboard - Left 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.
