Microcontrollers on boards using the ICL7660
What boards using the ICL7660 are built for
ICL7660: common questions
Where can I find a ICL7660 reference design?
Each of the 11 boards on this page is a real design using the ICL7660. 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 ICL7660 use?
Most are built on STM32 (1).
How big is a typical board using the ICL7660?
The median is 52 × 63 mm, and 82% are two-layer designs.
What is the most popular open source board using the ICL7660?
By GitHub stars, Leako by barbeque, with 20 stars.
Can I simulate one of these boards using the ICL7660 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.
