PW1-928 RF Data Transceiver Module

The PW1-928 RF transceiver module is designed for reliable bi-directional transfer of digital data over distances of over 300 feet in cluttered urban environments (over half a mile in true line of sight). Operating in the 902 to 928MHz frequency band, the module generates a nominal +7dBm into a 50-ohm load and achieves an outstanding RX sensitivity of –112dBm.

The module uses the industry standard LoRa direct sequence chirp spreading protocol combined with a proprietary data structure to both simplify user implementation and to significantly improve packet transmission reliability. It has a Universal Asynchronous Receiver Transmitter (UART) serial interface that can be directly connected to typical microcontrollers, RS-232 converters or USB adaptors. The module automatically handles all radio functions resulting in a true UART-to-antenna wireless link. Configuration setup is also accessed through the UART interface.

Features

  • True “asynchronous UART to antenna” solution
