4078: common questions
Where can I find a 4078 reference design?
Each of the 3 boards on this page is a real design using the 4078. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.
How big is a typical board using the 4078?
The median is 94.5 × 87.8 mm, and 67% are two-layer designs.
What is the most popular open source board using the 4078?
By GitHub stars, 8-bit computer Input Module by xrayer2000, with 30 stars.
Can I simulate one of these boards using the 4078 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.
