Most are built on AVR/Arduino (1).
How big is a typical board using the 4081?
The median is 98.5 × 88 mm, and 100% are two-layer designs.
What is the most popular open source board using the 4081?
By GitHub stars, SNES-FeRAM-Cart by soniccd123, with 87 stars.
Can I simulate one of these boards using the 4081 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.
