Waveshare 2.13inch E-Paper HAT+ for Raspberry Pi, SPI, HAT+ Standard

Building to the HAT+ standard means this display mounts and registers properly on compatible Raspberry Pi boards following the current hardware attachment convention, rather than an older, less consistently-supported HAT format. At 2.13 inches with genuine e-ink technology, it holds whatever image or text it last displayed with zero ongoing power draw, making it a natural fit for a Pi project that needs to show status information continuously without a backlit display burning power the whole time it's running. Its SPI interface keeps the wiring simple despite the e-ink driving electronics doing real work behind the scenes.
