Wi.M868X-DP-EVM-R™

The Wi.M868X-DP-R™ module is a microcontroller-less version of our popular Wi.232EUR-R™ module. It offers the same excellent RF performance, yet allows the design engineer to control the radio at the physical level using any microcontroller. Radiotronix recommends the new Wi.DP1203-868-EVM-R for new designs.

The module is footprint compatible with the DP1203 module from SemTech and can be used as a direct drop in replacement.

The Wi.M868X-DP-R™ is based on the XEMICS XE1203F transceiver RFIC. After evaluating all of the wireless Ics available, we chose the XE1203F as the heart of our Wi.™ Series of modules because it has by far the best performance and stability of all chips available today.

The module supports two modes of operation: wide-band and narrow-band. In wide-band mode, the channel width is 600kHz and in narrow-band mode the channel width is 200kHz.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.

Maximum transmit power is +15dBm. Maximum receive sensitivity is -112dBm. Receive sensitivity at the maximum baud rate is -103dBm typical. The transmitter draws 53mA typical at +15dBm. The receiver draws 14mA typical.

The Wi.M900X-DP-EVM-R™ is the 915MHz version.

This EVM can be used like a Wi.232DTS/EUR-EVM-R™ module in the Wi.™ evaluation board.
