Which microcontrollers do boards using the MCP23S08 use?
Most are built on ESP32 (1) and Nordic nRF (1).
How big is a typical board using the MCP23S08?
The median is 109.6 × 86.2 mm, and 100% are two-layer designs.
What is the most popular open source board using the MCP23S08?
By GitHub stars, Fusion by crides, with 82 stars.
Can I simulate one of these boards using the MCP23S08 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.
