3 open source boards using the ISO7321C
Real designs built with the ISO7321C, 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.

ISO7321C: common questions
Where can I find a ISO7321C reference design?
Each of the 3 boards on this page is a real design using the ISO7321C. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.
What parts are used alongside the ISO7321C?
The FT234XD, TPD3S014DBVR, 74LVC1G97, 74VHC541 and DS1683 appear in the most repositories here.
Which microcontrollers do boards using the ISO7321C use?
Most are built on PIC (3).
How big is a typical board using the ISO7321C?
The median is 200 × 50 mm, and 67% are two-layer designs.
What is the most popular open source board using the ISO7321C?
By GitHub stars, QI Charger by drewsum, with 20 stars.
Can I simulate one of these boards using the ISO7321C 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.
