TL;DR
The article discusses a practical tutorial by a maker named thanishurs31, showing how to reverse-engineer keyboard matrices using a Raspberry Pi Pico with CircuitPython. This method allows users to scan the entire keyboard matrix, identifying which pins correspond to rows and columns, while also accommodating various board types like diode-protected N-key rollover boards and simple membrane keyboards. The process culminates in generating a clean JSON map that represents the keyboard’s structure.
