4 open source boards using the PIR

Real designs built with the PIR, 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.

The PIR in open source designs

The gallery holds 4 open source boards using the PIR from 3 GitHub repositories; a typical one measures about 62.3 × 46 mm and carries around 48 components.

100% are two-layer designs, the rest use four layers or more, and 75% carry an open source license.

The most starred is SensePi rev5 main by Appiko.

Microcontrollers on boards using the PIR

What boards using the PIR are built for

PIR: common questions

Where can I find a PIR reference design?

Each of the 4 boards on this page is a real design using the PIR. 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 PIR use?

Most are built on Nordic nRF (2).

How big is a typical board using the PIR?

The median is 62.3 × 46 mm, and 100% are two-layer designs.

What is the most popular open source board using the PIR?

By GitHub stars, SensePi rev5 main by Appiko, with 2 stars.

Can I simulate one of these boards using the PIR 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.
