WIRL-BTLE Proteus-III Radio Modules

Würth Elektronik Proteus-III is a compact Bluetooth^® Low Energy (BLE) 5.1 radio module designed for wireless communication between control systems, sensors, and remote controls. It supports secure point-to-point data transmission using configurable firmware, allowing engineers to tailor performance to specific applications. Measuring 8 mm x 12 mm, the Proteus-III features an integrated PCB antenna and offers the option of an external antenna for extended range. The module communicates with the host system via a fast UART or SPI interface and is powered by the high-performance, low-power Nordic nRF52 series chip. It includes remote GPIO control and supports energy-efficient modes such as sleep and low-power position sensing. With its flexible design and comprehensive BLE features, the Proteus-III is ideal for projects requiring reliable and secure wireless connectivity.
