It seems like strapping a logic analyzer to the read connector, and an

I have to confess that I've never understood the Arduino thing. It
seems to be limiting the functionality of an MCU in the name of convenience.
An inexpensive STM32F4 or F7 MCU can have, depending on the package,
over 100 5V tolerant GPIOs, ...
5V tolerant does not mean 5V compatible. I have right now some 5V devices I want to
control, and it's not exactly clear whether a 3.3V device will drive outputs high
enough to reliably make 5V devices see them as high. Arduinos can be had in actual 5V
models (5V power, standard 5V logic levels in and out). Not the fast ARM ones but for
many purposes good enough.
