Which microcontrollers do boards using the 4040 use?
Most are built on AVR/Arduino (1).
How big is a typical board using the 4040?
The median is 147 × 99.8 mm, and 100% are two-layer designs.
What is the most popular open source board using the 4040?
By GitHub stars, Klangorium by hexagon5un, with 65 stars.
Can I simulate one of these boards using the 4040 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.
