DL-TRP433, 433MHz UART Serial Module with AXSEM AX5043 Chip

100mW UART Wireless Transparent Transmission Module 

DL-TRP Series RF Modules are high performance FSK wireless transparent transceiver modules with low-cost. 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. The 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.
