1. Introduction
The Radiotronix family of 868-870MHz and 902-928MHz embedded “Radio-Only” modules are designed to meet
European and US certification requirements.
This family consists of the Wi.M868/900X-R™, Wi.M868/900T-R™, and the Wi.M868/900X-DP-R™ modules.
These modules are
microcontroller. The Wi.M868/900T-R ™is a transmit only radio while the Wi.M868/900X-R™ is a transceiver
only radio module.
The embedded only modules are footprint compatible with the Radiotronix family of Microcontroller + SW protocol
versions in both 902-928MHz (Wi.232DTS-R and Wi.232FHSS-25-R) radio modules and the 868-870MHz Euro
module (868-870 MHz). This allows the designer a flexible platform to start work with fully transparent serial
UART solutions and later move to the lower cost microcontroller-less radio only versions.
The Wi.M868/900X-DP-R, transceiver only radio was designed as a footprint compatible module with the
Semtech DP1203-868/915 modules. For new designs, it is recommended that the designer goes with the
Wi.DP1203-868/915-R module which is a direct replacement for the Semtech module.
The Wi.M900™ modules support 32 wide band high power channels and 84 narrow band low power channels.
The Wi.M868™ modules support two modes of operation: wide-band (2 channels) and narrow-band (6
channels). In wide-band mode, the channel width is 600 kHz and in narrow-band mode the channel width is 200
kHz. The module is configured via a simple SPI style serial interface. Data is transmitted and received using a
separate digital serial interface that includes pre-amble and start-of-packet detection.
The radios are capable of +15dBm on chip power output with a -112 RF sensitivity. The RF data rate is 152.34
with UART data rates selectable from 1.2kbps to 115kbps.
A typical circuit consists of a low-cost microcontroller, a power source, an embedded module, and an antenna.
