The RasPi has heaps of GPIO too - I'm wondering if the likes of a 'zero' could take some of the 'control ' and display functions from the Raduino? Would/could I^2C tie them? There must be a heap of non-critical stuff not? absolutely dependent on the microprocessor immediacy? A zero-W could give Internet remote ops too! (or has that already been thrashed and trashed?)
