433Mhz UART Serial Communication Wireless Transceiver Module with SI4463 Chip


DL-RTS4463M is a Wireless Data Transparent Transmission Module with UART Communication, it was designed base on Siliconlabs' new generation chip SI4463. This RF Module has high integration and ultra-high performance, with low power consumption, which adopts spread spectrum communication technology, and has the characteristics of long transmission distance (2100M), extremely high sensitivity (-121dBm), super anti-interference ability, flexible to use, and convenient parameter configuration. 

This wireless module adopts highly efficient cyclic interleaving error correction coding, which greatly improves its anti-interference ability and sensitivity. It provides multiple channel selections, and support parameters online modification, such as serial port rate, transceiver frequency, transmit power, RF rate and other important parameters. The working voltage of DL-RTS4463M module is 2.1V-3.6V, and the working voltage of 3.5V-5.5V can be customized. In the receiving state, it only consumes 15mA current.

This module is an excellent RF Transparent Transmission Module, which has a good radio frequency performance; it uses single-chip architecture, combined with a cost-effective low-power MCU, electronic switches, high-precision chip crystal, etc. There are four modes of this RF module: any mode can be switched arbitrarily. In the 1SEC cycle polling wake-up power-saving mode, the receiving current consumes only tens of microamperes, and a 3.6V / 3.6AH battery can work for several years, which is very suitable for battery-powered system.


Features:

● 1-2 kilometers transmission distance (depends on rate, antenna performance)

● Efficient cyclic interleaving error correction coding

● Working frequency: 433.92M (other frequencies need to be customized)

● Half-duplex, one-to-one, one-to-many applications

● Data buffer 256Byte, sleep 1uA

● Working temperature: -30 ℃ ~ + 75 ℃
