Microcontrollers on boards using the ISO7740
ISO7740: common questions
Where can I find a ISO7740 reference design?
Each of the 1 boards on this page is a real design using the ISO7740. 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 ISO7740 use?
Most are built on AVR/Arduino (1).
How big is a typical board using the ISO7740?
The median is 75.7 × 36.8 mm, and 0% are two-layer designs.
What is the most popular open source board using the ISO7740?
By GitHub stars, RTB C02 by git4dcc, with 4 stars.
Can I simulate one of these boards using the ISO7740 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.
