OpenEPaperLink Screen — Hanshow Nebular 420

Repurposed retail shelf-label e-ink screen flashed for smart-home/DIY displays.

Physical productone_time

Takes a decommissioned Hanshow Nebular 420 electronic shelf label (used in stores as a price tag) and reflashes it with OpenEPaperLink firmware so it can be used as a low-power e-ink display for smart-home dashboards, IoT status panels, calendar/weather boards, and Home Assistant integrations — far cheaper than buying a purpose-built e-ink display module new.
