6 open source boards using the 4050
Real designs built with the 4050, 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.

What boards using the 4050 are built for
4050: common questions
Where can I find a 4050 reference design?
Each of the 6 boards on this page is a real design using the 4050. 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 4050 use?
Most are built on AVR/Arduino (3).
How big is a typical board using the 4050?
The median is 216.6 × 152.9 mm, and 100% are two-layer designs.
What is the most popular open source board using the 4050?
By GitHub stars, MegaMIDI by AidanHockey5, with 116 stars.
Can I simulate one of these boards using the 4050 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.
