1W UART Wireless Transparent Transmission Module 

DL-TRP B Series Wireless Modules are medium power, high performance FSK wireless transparent data transceiver modules. They can work in 433/470/868/915MHz ISM band, compact in size, but large power, high sensitivity, long transmission distance, and high communication rate; they can automatically complete communication protocol conversion and data receive control within the module. This module provides UART serial data interface, which enables wireless data transmission by providing only serial data. Users can also flexibly configure the serial rate,operating frequency, transmission power, communication rate, modulation frequency offset, receiving bandwidth and other parameters of the module according to their own needs.

DL-TRP series modules can be widely used in all kinds of wireless data transmission fields, and are ideal for designing wireless data transmission products.


● High power output, high performance RF parameters and high reliability;

● FSK modulation, half duplex communication, strong anti interference ability

● A series 433 / 470 / 868 / 915MHz ISM frequency band, no need to apply for frequency point

● The maximum output power is 1W (30dBm), and the output power can be adjusted

nonlinearly in the range of 20-27dbm;

● The module adopts single power input, low noise DC chip supplies power to RF and PA

respectively, and the receiving sensitivity is - 117dbm;
