URF radio module and serial inteface via USB (CISECO R002)

An extremely affordable, easy to use RF serial data module with great range pre-built with a USB connector.

Provides an out-of-the-box wireless RF serial connection without the need for programming or end-user configuration.

Comes pre-loaded with Ciseco firmware which enables the URF to interwork with all other Ciseco RF modules, without any programming or configuration. You provide data one end and it appears on the other. All data packetisation, data checking, etc. is all done for you.

Makes use of Texas Instruments’ CC1111, a low-power System-on-Chip, which sports a micro-controller unit (MCU), memory, a sub-1GHz transceiver, an encryption engine and a USB controller.

Key Features:

• Comes pre-built
• Supports network identifier PANID for communications into separate networks if desired
• Full speed USB controller (12Mbps)
• 868 and 915 MHz ISM/SRD bands
• 250kbps transfer rate
• 10dBm (10 mW) power
• Low current consumption (RX: 24mA; TX: 36mA @ -10dBm output power)
• Facilitates remote Arduino/Xino over-the-air programming
• RoHS
• CE
• WEEE
• Made in the UK

Applications:

• Low power wireless applications operating in the 868 and 915 MHz ISM/SRD bands
• Industrial monitoring and control
• Wireless sensor networks
• Wireless alarm and security systems
• Automatic meter reading
• Home and building automation
• Low power telemetry

Limitations to use:

The URF is not recommended or authorised for use in life support, surgical implantation, nuclear or aircraft applications or for any use or application in which the failure of a single component could cause substantial harm to persons or property.

The URF is usually combined with sensors and actuators communicating via other Cisecoradios.

It is often more convenient to use the SRF stick, which is more robust as it has an enclosure.
