The Circuit Playground E-Ink Gizmo is a bolt-on expansion that adds a 1.54" tri-colour e-ink display, two STEMMA connectors, and a Class D audio amplifier to your Circuit Playground board. It attaches mechanically and electrically via pre-soldered M3 standoffs — no soldering or wiring required.

The 200×200 pixel e-ink display renders black and red ink on a white background, offering high contrast and excellent daylight readability. Like all e-ink panels, the image persists even when power is disconnected, making it ideal for status displays, badges, and signage.

Key Features
