making a GPIO an EINT on the STM32F, then reading I2C, then sending a
few bytes of data as a USB event, it's about... 30-40 lines of code.
if it's any more than that, you're doing something *drastically*

honestly it's up to you. personally i just went for standard 0.254mm
connectors, because that *really* makes it easy for developers.
however, they're quite big, you need to get R/A ones, and i believe
those could well be more expensive than a 6pin FFC.
so it is your decision, you know what the goal is, available space,
target price and target market.
