NFC + BLE Smart Tag
ST25DV NFC + nRF52 BLE, e-paper display
About this design
A combined NFC + BLE tag with an e-paper display. NFC for tap-to-pair and provisioning, BLE 5.0 for live data, e-paper for always-on visible state. ST25DV NFC + nRF52 BLE SoC, coin-cell powered.
Typical applications
Retail electronic shelf labels, asset identification with status readout, conference badges with live agenda updates, inventory pick-by-tap warehouse workflows.
Compliance scope
RED, EN 300 330 (NFC 13.56MHz), EN 300 328 (BLE 2.4GHz), EN 62479, EN 55032/35.
