To ensure prices displayed on store shelves are always accurate or to instantly launch promotional campaigns, the use of Electronic Shelf Labels (ESLs) is now widespread in grocery stores. An ESL can receive information in several ways including indoor infrared, Bluetooth Low Energy (BLE) or other proprietary wireless connectivity technologies. Based on LCD or electronic paper (e-INK) display technologies, the key factor is battery life, which can be as high as 10 years. ESLs can also include an NFC interface to enable customer engagement, parameter configuration and firmware uploads.

Our ultra-low-power STM32L and STM8L microcontrollers help extend battery life while providing direct control of the LCD or e-INK display modules. In addition, we offer BLE connectivity and dual-interface Dynamic NFC tag solutions.
