Generally, actual industry would use the pi compute module instead of the pi itself, and you plug the compute module into a carrier board with better power, storage, and IO options (i.e., rs485, 24V DC, eMMC instead of SD, etc)

One of a million examples: https://pipci.jeffgeerling.com/boards_cm/edatec-cm4-industri...

Having your power connector come loose on a vibrating machine or having your SD card die is a serious problem when you're trying to use a machine to make money reliably and consistently.

Anyway that's unrelated to GP really, raspberry pi sucks too much power for playdate, I think.
