Which microcontrollers do boards using the 8255A use?
Most are built on AVR/Arduino (1).
How big is a typical board using the 8255A?
The median is 100 × 100 mm, and 100% are two-layer designs.
What is the most popular open source board using the 8255A?
By GitHub stars, EProg by KALTCHUK, with 94 stars.
Can I simulate one of these boards using the 8255A 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.
