The MN52M ultra-low power series, powered by Nordic Semiconductor's nRF52811 chipset, is the Bluetooth 5 version of the Bluetooth® Association's module solution. It provides developers with great design flexibility and an outstanding 4dBm RF signaling capability. The nRF52811 is a complete multi-protocol embedded wireless microprocessor product that combines low power consumption with a high degree of flexibility for developers to maximize their design concepts, product applications and mass production.

nRF52811 chip, is a general-purpose multi-protocol SoC, built-in Contex M4 microsystem, and configured with 192MB of non-volatile memory and 24KB of random-access memory, providing users with more design and code storage space, which is conducive to enabling the production of more design and flexible applications. 32 GPIO versatility can be set via software, supports NFC-A tag for access control and quick configuration applications, 1.7V to 3.6V voltage input. It supports low power Bluetooth, including high transmission speed of 2 Mbps. Bluetooth Mesh Networking can run alongside low-power Bluetooth, enabling smartphones to provision, connect, configure and control mesh network nodes. ANT and 2.4 GHz and long ragne proprietary protocols are also supported. Examples, libraries, and drivers are provided to make it easy to get started.
