Cute I guess, though no idea why I'd want an e-ink name badge. I wish there were more affordable large e-ink screens. These tiny ones don't do much for me. It does seem to me that the rpi pico is maybe the goto cheap MCU board these days. Not much reason to use a blue pill or arduino clone any more, unless I've missed something.

I did think that drag-drop micro python (or is it circuit p) programming method was odd but maybe it's different now. I personally am trying different stuff out. I've used Arduino/Teensy/ESP/Pi (OS) but I have a blue pill and beagle bone as well to mess around with. The RP2040 does seem to have a lot of IO anyway.

check ebay for eInk price tags. They are a great source of case+battery+enclosure+screen for $little

Check out Inkplate for larger, affordable, ready-to-program, e-ink screens - they have both 6" and 10", and even color! https://www.crowdsupply.com/soldered/inkplate-6 https://www.crowdsupply.com/soldered/inkplate-6 https://www.crowdsupply.com/soldered/inkplate-10 https://www.crowdsupply.com/soldered/inkplate-10 https://www.crowdsupply.com/soldered/inkplate-6color https://www.crowdsupply.com/soldered/inkplate-6color

  Those look nice, and they are larger, but they're also 10X the price?

  Yeah I know about the inkplate, I might get the 10", or maybe they will do a 10+ analogously to the 6+, but I'd like an even bigger one. The ipad pro that everyone wants is 12.9" and a letter sized sheet of paper is 14" so I'd want to start up in that range, for reading stuff like arxiv pdf's. I do know about epaper shelf tags but that is pretty niche imho. Not that many of us are involved in stocking store shelves.

How much more power hungry is the dual-core Arm Cortex-M0+ chip vs. the ATmega328P?

  At base clocks the mega will use half the power. Though unsure what gains you would recoup with the pico by reducing the clock, so maybe pico could match and surpase at a lower clock speed.

It's definitely the goto cheap MCU for me now, for one reason: it's in stock. It's nice that industry doesn't take it seriously.

You might look at the M5paper? Esp32 based, so wifi, 4.7" eInk. I haven't used one, but it looks neat. https://docs.m5stack.com/en/core/m5paper https://docs.m5stack.com/en/core/m5paper

  I did look at that and it is interesting and kind of tempting. I want a lot bigger though. Thanks.
