A battery-free 4-color e-Paper that updates with a tap — no wires, no power port.

The Waveshare 1.54" NFC e-Paper (200×200, 4-color) harvests all its power from the NFC field. A MIKROE NFC 4 Click (ST25R3916) driven by an ESP32-C5 over SPI @ 2 MHz sends each image over ISO-DEP. Every tap loads the next picture, and the panel keeps it on-screen with zero power.
