1 Introduction
1.1 Purpose& Description
DSM-04D is a low power-consuming embedded Zigbee/matter/BLE module developed By Dusun. It
consists of the highly integrated wireless radio processor chip, EFR32MG24A020F1536IM40-B, and several
peripherals, with a built-in 802.15.4 PHY/MAC Zigbee/matter/BLE network protocol stack and robust
library functions.
This data terminal device is embedded with a low power-consuming 32-bit ARM Cortex-M33 core,
1024/1536 KB flash memory, 256 KB RAM data memory, and robust peripheral resources. Besides, it runs
on the Free RTOS platform that integrates all Zigbee/matter/BLE MAC library functions. You can develop
built-in Zigbee/matter/BLE products as required.
