IC revision2.0

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

Ultralow power wireless STM32WB09KE microcontroller based on the Arm Cortex®‑M0+ core, featuring 512 Kbytes of flash memory and 64 Kbytes of SRAM in a VFQFPN32 packageSupports Bluetooth® LE SIG specification v5.4 PAwR featureST25DV04KC-IE6C3 dynamic NFC/RFID tag IC with 4-Kbit EEPROMOn-board 2.4 GHz PCB antennaOn-board 13.56 MHz inductive antennaSTLINK-V3SET target connectorUser LEDUser and reset push buttons1.54 inches E-Ink displayCR2032 battery holderDedicated STM32 hotspot containing firmware and setup guide
