Description
The STEVAL-ESL1KCB is a modular application example of a wireless electronic shelf label (ESL) featuring Bluetooth® LE and NFC connectivity. The kit includes two boards.The STEVAL-ESLWB0CB with the ultralow power wireless STM32WB09KE microcontroller grants the communication with another Bluetooth® LE device acting as an access point to set the ESL display (price, text, icons) via PAwR packets.The STEVAL-ESLST25CB with the ST25DV04KC dynamic NFC/RFID tag IC stores more product information like the address of a web page.The STEVAL-ESLWB0CB can run the ESL application STM32WB0-BLE-PAwR-ESL.
Features
