From the project

The Split 65% Keyboard - AVR Based

This is a custom 65% style keyboard that is split in the middle to provide a more ergonomic option whilst not being drastically different from the standard stagger used on keyboards

In the below image you can see the different options available, the top four rows represent the four rows of th keyboard and the options for the final keyboard row is represented by the remaining rows in the image.

TS65AVR: common questions

What microcontroller does the TS65AVR use?

The TS65AVR is built around the Atmega32u4, from the AVR/Arduino family.

How big is the TS65AVR PCB?

The TS65AVR measures 299.5 × 105.8 mm and is 1.6002 mm thick.

How many components are on the TS65AVR?

428 components, from 42 distinct parts. The full bill of materials is listed on this page.

Where can I download the TS65AVR design files?

From the mohitg11/TS65AVR repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the TS65AVR design in my own project?

The repository has no license, so all rights stay with mohitg11. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the TS65AVR 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.
