I'm working on optimizing some of my wife's ecommerce fulfillment and want to use e-ink labels on racks to help her organize and optimize her process.  I've found some systems on Aliexpress or labels that can be hacked, however these require a base station or android app to manually program.  Curious if anyone knows of a brand or source that is equivalent to an ESP32 attached to a small e-ink display with high enough resolution to render a pdf417 qr code?Must haves are:- long battery life
- wifi networking to update display OTA
- basic docs to use python / c to communicate with deviceThanks!
