What boards using the 4011 are built for
4011: common questions
Where can I find a 4011 reference design?
Each of the 20 boards on this page is a real design using the 4011. 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 4011?
The 4013, 4001, 4071, 4023 and 4049 appear in the most repositories here.
Which microcontrollers do boards using the 4011 use?
Most are built on AVR/Arduino (3).
How big is a typical board using the 4011?
The median is 100 × 100 mm, and 100% are two-layer designs.
What is the most popular open source board using the 4011?
By GitHub stars, PLC-14500 by nicolacimmino, with 69 stars.
Can I simulate one of these boards using the 4011 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.
