LPRS ERA900TRS 射频模块, ISM 收发器, 868MHZ
This module includes the ability to change bandwidth of the radio from 19.2KHz down to 12.5KHz, which means narrow-band performance. Internal temperature measurement ensures less than 1.5KHz frequency drift from ambient 20°C, over a range of -40°C to +85°C, as well as providing a usable thermometer for the connected application accurate to within 1°C. Modes of transmission include a protocol with 16-bit encryption and anti-cross talk software, plus raw data modes where users can use self-coding system which can be set to interface to any other raw data module on ISM bands in both FSK and ASM modulation.
