Würth Elektronik presents the Bluetooth Low Energy 5.1 module Proteus-III-SPI. The module, measuring only 8 × 12 × 2 mm, with a payload of up to 964 bytes, integrated antenna, encryption technology and six configurable IO pins, is based on the Nordic Semiconductor nRF52840 chipset. It can be used for IoT and M2M applications, for example, to build radio-based maintenance interfaces and sensor networks. The WE-ProWare firmware from Würth Elektronik, which has been industrial proven over many years, makes the module extremely versatile.
