Overview

DSM-050 is a low-power embedded Bluetooth v5.2 module. It is composed of a highly integrated wireless chip nRF52840 and some peripheral devices. 

 

The antenna is on board PCB Antenna with 2.0dBi gain. This module supports Mesh protocol and long range protocol and is suitable for smart home device.

This module can be built-in a series of different Bluetooth IoT product firmware, can realize product design without development. This can greatly reduce the product development cycle and quickly go to market. 

 

Otherwise, it can be equipped with Dusun Bluetooth gateway, which will provide MQTT documents for free, and quickly connect to public cloud platforms or private platforms.
