1 open source board using the Add/Sub
Real designs built with the Add/Sub, from public GitHub projects: a quick way to see how others power, decouple and connect it. Each board comes with its KiCad files, full parts list and a render — and you can simulate its firmware on HardLabs.

What boards using the Add/Sub are built for
Add/Sub: common questions
Where can I find a Add/Sub reference design?
Each of the 1 boards on this page is a real design using the Add/Sub. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.
How big is a typical board using the Add/Sub?
The median is 132.1 × 114.3 mm, and 100% are two-layer designs.
What is the most popular open source board using the Add/Sub?
By GitHub stars, Alu back by Velko, with 16 stars.
Can I simulate one of these boards using the Add/Sub before building it?
Yes. HardLabs turns a board's netlist and BOM into a working simulation, so you can boot and test firmware against it with no hardware on your desk.
