The evaluation kit includes two of these modules, with in-built power supply, an RS232 serial interface and an antenna.

The ER400TRS is an extremely compact intelligent radio transceiver that operates in the 434MHZ LIPD band. This UK designed and manufactured device integrates radio, microcontroller and power supply circuitry in a screened 9-pin single-in-line module measuring just 37 x 14 x 4mm. All communications protocols are handled on-board, allowing OEMs to add wireless capabilities to their products without the need to understand radio technology.

One obvious application for these new modules is in two-way data telemetry systems. They would also be suitable for applications where it is essential that a receiving node issues a "receipt" to confirm reception of transmitted data, such as in handheld terminals and electronic point-of-sale terminals.

The ER400TRS transceiver is supplied ready-to-run from LPRS. Alternatively, designers can make use of a range of user-programmable functions to customise their radio links to their own specifications using simple software commands.
