11 open source boards using the ISO1540
Real designs built with the ISO1540, 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 ISO1540 are built for
ISO1540: common questions
Where can I find a ISO1540 reference design?
Each of the 11 boards on this page is a real design using the ISO1540. 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 ISO1540 use?
Most are built on NXP (2), STM32 (2), AVR/Arduino (1) and PIC (1).
How big is a typical board using the ISO1540?
The median is 85.5 × 57.2 mm, and 55% are two-layer designs.
What is the most popular open source board using the ISO1540?
By GitHub stars, I2c by multigcs, with 91 stars.
Can I simulate one of these boards using the ISO1540 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.
