Product Description

 SZ05-L-STD-3 Zigbee module

SZ05-L-STD-3 Zigbee module

First, product introduction

The SZ05-L-STD-3 wireless data transmission module adopts TI's chip and conforms to the Zigbee pro international standard RF transceiver and microprocessor. It has long communication distance, ultra-low power consumption, strong anti-interference ability and flexible networking. Advantages and features; practical MESH networking. The SZ05-L-STD-3 data transmission module implements transparent transmission of TTL serial data. The SZ05-L-STD-3 data transmission module acts as a terminal node to transmit and receive data only.

The SZ05-L-STD-3 devices are part of the CC26XX family of cost-effective ultra-low power 2.4GHz RF devices with very low active RF and MCU currents and low power mode current consumption. Therefore, Shunzhou Intelligent SZ05-L-STD-3 ultra-low power module fully meets the requirements of the Internet of Things for low power consumption, and is very suitable for battery-powered, small-sized smart home, RFID, network sensor, security and access control. And wireless connectivity products such as remote control.
