This article introduces OpenMote+, a prototyping platform designed for the Industrial Internet of Things (IIoT). The OpenMote+ offers a dual-radio interface for short- and long-range communications, supporting the most prominent physical and MAC (Medium Access Control) layer standards, such as IEEE 802.15.4e, IEEE 802.15.4g and 6TiSCH, and a contact-based interface based on NFC (Near Field Communications) to address the operational aspects of a network deployment, such as security key distribution and in-situ reprogramming. The OpenMote+ platform is complemented by support of the most popular open-source IIoT implementations today, such as OpenWSN, Contiki and RiOT.
