This PCB looks just like a round E-Ink breakout but has permanently affixed M3 standoffs that act as mechanical and electrical connections. They have gigantic electronic paper 'static' displays - that means the image stays on the display even when power is completely disconnected.
Once attached you'll get a 1.54" 152x152 display (black and red ink pixels and a white-ish background), two 3-pin STEMMA connectors for attaching NeoPixel strips or servos, and a Class D audio amplifier with a Molex PicoBlade connector that can plug one of our lil speakers.
