I'm a bit confused about the Pyboard. Do people buy Pyboards instead of ESP32 in order to support the project, or because they are more featureful, or both? Why does the Pyboard have a CPU in addition to the microcontroller, does the microcontroller only deal with IO?
Quick search shows the v1.1 at least it's just a microcontroller and a uSD slot. So I'd imagine it's just about support. With all the ESP32 boards out there, sky's the limit on word behavior you could get from flaky hardware.
