Microcontrollers on boards using the ISO6721 / ISO7721
ISO6721 / ISO7721: common questions
Where can I find a ISO6721 / ISO7721 reference design?
Each of the 1 boards on this page is a real design using the ISO6721 / ISO7721. 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 ISO6721 / ISO7721 use?
Most are built on STM32 (1).
How big is a typical board using the ISO6721 / ISO7721?
The median is 58.4 × 83.2 mm, and 100% are two-layer designs.
What is the most popular open source board using the ISO6721 / ISO7721?
By GitHub stars, MiniFeedMaster by SG-O, with 1 stars.
Can I simulate one of these boards using the ISO6721 / ISO7721 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.
