It is a dual-core Arm Cortex-M0+ with about 262 kilobytes of RAM. The feature I like most is the programmable IO pins. These are small state machines that run independently of the Arm cores. They allow for some clever tricks. For example, I used them extensively on the Mega IIe project. This video was supposed to be a project I thought of during the Mega IIe. I call it a state-mode logic analyzer. However, it took me several days to turn on and debug four boards. Time ran out, so I focused the video on debugging custom RP2040-based boards. These are all lessons I have learned from this project, plus about another dozen RP2040 boards I have built over the past couple of years.
