From the project

40% staggered through-hole component keyboard PCB for standard 60% cases

Rosaline is a 40% keyboard PCB using through-hole components for that visible component aesthetic.

The goal of this project is to build an all through-hole component 40% PCB that fits in a standard 60% tray mount case.

Designed to be easy to build with minimal soldering experience. All through-hole components, no SMD soldering required. Get that visible component aesthetic in a standard 60% tray-mount case. Staggered and ortholinear varieties. * Supports both USB Mini and USB-C.

Rosaline ortho: common questions

What microcontroller does the Rosaline ortho use?

The Rosaline ortho is built around the ATMEGA328-PU, from the AVR/Arduino family.

How big is the Rosaline ortho PCB?

The Rosaline ortho measures 285.4 × 94.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Rosaline ortho?

148 components, from 81 distinct parts. The full bill of materials is listed on this page.

Where can I download the Rosaline ortho design files?

From the peej/rosaline-keyboard repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Rosaline ortho design in my own project?

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

Can I test firmware for the Rosaline ortho 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.
