The TRM-915-R25 is part of the 25 Series RF transceiver module from Linx Technologies which designed for bi-directional digital data transfers of up to 1 mile (1.6 km) line of sight applications. It
operates at a frequency range between 902 to 928 MHz and is capable of generating 13 dBm of power (Matched to 50 Ohms) and has a receive sensitivity of -105 dBm.
The module implements a Frequency Hopping Spread Spectrum (FHSS) protocol along with networking and assured delivery features. It has a Universal Asynchronous Receiver Transmitter (UART) serial interface that can be connected directly to microcontrollers, RS-232 converters or USB adaptors. The module automatically handles all radio functions resulting in a UART-to-antenna wireless link. All configuration settings and data are accessed through the UART interface.
