Microcontrollers on boards using the HEF4093B
What boards using the HEF4093B are built for
HEF4093B: common questions
Where can I find a HEF4093B reference design?
Each of the 12 boards on this page is a real design using the HEF4093B. 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 HEF4093B use?
Most are built on AVR/Arduino (2) and STM32 (1).
How big is a typical board using the HEF4093B?
The median is 75.4 × 91.4 mm, and 100% are two-layer designs.
What is the most popular open source board using the HEF4093B?
By GitHub stars, 3-phase lfo by tpcarlson, with 106 stars.
Can I simulate one of these boards using the HEF4093B 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.
