The ZETA-868-SO module is a RF Solutions sub-GHz module that operates in the 868MHz frequency range, which is a common industrial, scientific, and medical (ISM) frequency band. This module features multiple radio interfacing with communications switching between Transceivers (Tx) and Receivers (Rx). It also has a multi-channel heterodyne receiver that offers high sensitivity and selectivity, as well as excellent noise immunity. This module also has a programmable Atemel microcontroller, which allows for remote programmability and custom configuration of the device. The ZETA-868-SO module is a small, easy to use device, making it ideal for applications that require rapid, reliable, and low-power communication.
