The LumenRadio MWA-N2 (Mira Wide Area) module is an industrial grade, long-range, multi-standard radio module, designed for high volume production. MWA-N2 is based on the Nordic Semiconductor nRF52840 and features a powerful ARM Cortex M4 microcontroller and a dual radio for Bluetooth-based protocols and 802.15.4-based protocols. MWA-N2 is optimized for running MiraOS and the MiraMesh radio stack.

The MiraOS, MSS (Multi-Standard Support) feature allows concurrent operation of MiraMesh and Bluetooth v5.0, as well as NFC. This feature provides reliable mesh networking through MiraMesh with concurrent support for easy commissioning, local control and user interaction (UX/UI) over Bluetooth v5.0/NFC using a smartphone or tablet. Ultra-low energy consumption allows for battery-powered products or energy harvesting operation. MWA-N2 is an SMD module and thanks to its small footprint it it can be easily be integrated into any product. Best-in-class range (+1000m line-of-sight), thanks to the built-in PA and LNA.
