E-Ink displays provide a paper-like viewing experience that is always on, using virtually zero power to maintain the display. Build a stylish wall-mounted dashboard with your Raspberry Pi that shows weather, calendar events, to-do lists, and news — visible even in direct sunlight without any backlight glare.
Why E-Ink for Raspberry Pi Dashboards
Why E-Ink for Raspberry Pi Dashboards is a fundamental concept for this project. Understanding the basics will help you configure your Raspberry Pi optimally for this use case.
Choosing an E-Ink Display
- Raspberry Pi 4 or 5 (4GB+ recommended)
- MicroSD card (32GB+) or NVMe SSD for better performance
- Ethernet connection for reliable networking
- Appropriate case and cooling for 24/7 operation

How long does the display last without power?
E-Ink displays retain their image indefinitely without power. Once content is written to the screen, it stays visible even if you disconnect the Pi. This makes it perfect for low-refresh dashboards.
How often can I update an E-Ink display?
Most E-Ink displays support full refresh every 3-180 seconds. Partial refresh (faster, but may ghost) can happen every few seconds. For a dashboard, updating every 5-15 minutes is ideal.
Which E-Ink display size is best for a dashboard?
7.5-inch displays (800×480) offer a good balance of readability and cost (₹3,000-4,000). For a wall-mounted calendar, 10.3-inch or larger is better but significantly more expensive.
Can E-Ink displays show colour?
Most affordable E-Ink displays are black and white (some with red or yellow as a third colour). Full colour E-Ink exists but is expensive and slow to refresh. For dashboards, black/white/red is sufficient.
