UART Serial Communication Transparent Transmission RF Module with AXSEM AX5043 Chip:


DL-RTA5043M is a 50mW narrowband transmission (power centralized) wireless data transmission module based on AX5043 RF chip from Swiss AXSEM. It works in 407-450MHz ISM band and uses serial port for data transmission, which lowers the threshold of wireless application.

Narrow-band transmission has the advantages of concentrated power density, long transmission distance and strong anti-jamming ability, and greatly increases transmission distance compared with other similar products at the same power. This module can configure FEC forward error correction algorithm, which has high encoding efficiency and strong error correction ability. It can actively correct the jammed packets in case of sudden interference, greatly improving the reliability and transmission distance.

This UART serial module has data encryption and compression capabilities. The transmit data in the air is random but with rigorous encryption and decryption, which makes data interception meaningless.

The data compression function has the probability to reduce the transmission time, reduce the probability of interference, and improve the reliability and transmission efficiency. This RF module can operate in a wide voltage range of 2.1 - 5.5V to meet the needs of battery power supply. The module has four working modes, can switch freely during operation, consumes only tens of microamperes of current in power-saving mode, and is ideal for ultra-low power system and sensor applications.
