Which microcontrollers do boards using the ATmega328-AU use?
Most are built on AVR/Arduino (13).
How big is a typical board using the ATmega328-AU?
The median is 54.6 × 77.5 mm, and 92% are two-layer designs.
What is the most popular open source board using the ATmega328-AU?
By GitHub stars, PaperBack Converter by dqydj, with 83 stars.
Can I simulate one of these boards using the ATmega328-AU 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.
