4 open source boards using the ISO1541
Real designs built with the ISO1541, 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 ISO1541
What boards using the ISO1541 are built for
ISO1541: common questions
Where can I find a ISO1541 reference design?
Each of the 4 boards on this page is a real design using the ISO1541. 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 ISO1541 use?
Most are built on AVR/Arduino (1), PIC (1) and STM32 (1).
How big is a typical board using the ISO1541?
The median is 145 × 85.8 mm, and 100% are two-layer designs.
What is the most popular open source board using the ISO1541?
By GitHub stars, Garden Irrigation Motherboard by vinthewrench, with 2 stars.
Can I simulate one of these boards using the ISO1541 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.
