“Great e ink display for such a good price, and well thought out power set up allowing it to be completely halted and woken again by a button press. I've had it running off a single coin cell, but that's only possible by underclocking it using the C++ SDK. For micropython you need three in parallel to keep it stable, or Lipo/AAA batteries as recommended in the description!”
“Fantastic bit of kit, great for learning about the RP2040 and useful too! I've hacked it to be a simple square wave generator with an adjustable frequency up to 12.5Mhz, with an adjustable duty cycle. I used the Scoppy oscilloscope app with an RP2040 to test it.”
“Lovely ePaper display, an RP2040 based controller, some buttons and an LED - so much more than just a fancy badge, and only £12. It's the bargain of the year.”
“I was able to use it immediately by referring to Getting Started with Badger 2040.
It is good that the display does not disappear.
It's great if you can use Japanese fonts!”
“I am not one for attending conferences but this is sort of an interesting device that I will eventually find a use for. The low power requirements and the time required to update the e-ink display suggest a battery-powered project that doesn't require constant updates.”
“This devboard is such a cool idea! The display has a nice contrast ratio and it is very well built and lightweight. Not to mention the super cool art in it.”
