2 open source boards using the DAC
Real designs built with the DAC, 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.

Microcontrollers on boards using the DAC
DAC: common questions
Where can I find a DAC reference design?
Each of the 2 boards on this page is a real design using the DAC. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.
Which microcontrollers do boards using the DAC use?
Most are built on AVR/Arduino (1) and PIC (1).
How big is a typical board using the DAC?
The median is 109.8 × 95.8 mm, and 100% are two-layer designs.
What is the most popular open source board using the DAC?
By GitHub stars, ExpEYES Junior by expeyes, with 18 stars.
Can I simulate one of these boards using the DAC 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.
