Product description

The LumenRadio MLE-N2 (Mira Low Energy) module is a small size, cost efficient, industrial grade, multi-standard radio module, designed for high volume production of products without the need of an external antenna.

MLE-N2 is based on the Nordic Semiconductor nRF52840 and features a powerful ARM Cortex M4 microcontroller with a dual radio for Bluetooth-based protocols and 802.15.4-based protocols. MLE-N2 is optimized for low-energy applications built on 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. MLE-N2 is an SMD module and thanks to its small footprint it can easily be integrated into any product.
