The eRA (easyRadio Advanced) modules are available in two frequency bands: eRA400TS  and eRA400TRS for European 433 MHz licence-exempt ISM band, eRA900TRS-FCC dual band for European 868MHz and USA 907 - 923 MHz licence-exempt ISM bands.  

More about eRA Modules

The eRA (easyRadio Advanced) software allows developers to change many of the parameters of the radio to suit the individual application. The bandwidth of the module may be adjusted between 100KHz and 12.5KHz giving narrow-band performance on a wide-band budget. A user configurable self-coding system enables interfacing to other raw data modules in both FSK (FM) and ASK (AM) modulation modes.

Other features include a digital received signal strength indication (RSSI), reducing the requirement of the host system to handle A-D measurements. The RSSI signal may be delivered as a simple command for either the current RSSI level or the signal strength of the last received packet. eRA also allows a temporary channel selection allowing the host to scan other channels in real time without storing settings on the internal EEPROM thereby maximising the life of the EEPROM.

Users may programme transmission frequency (up to 132 channels), output power (up to 10mW), serial data rate (up to 115.20Kbps maximum), digital RSSI, carrier detect, FSK and ASK modulation and bandwidths (12.5KHz, 25KHz, 50KHz, 100KHz).

To maintain frequency accuracy within +/- 1KHz over the module’s full operating temperature range of -40 to +85ºC, temperature compensation of the crystal controlled synthesiser is accomplished using the on-board temperature sensor which may be used by the host system.

The LPRS eRA range is comprised of 433-434MHz and an 868 to 920MHz multi-frequency transmitter and transceiver modules plus a development kit with a USB interface. Applications for the eRA wireless modules include building and home automation, sports and leisure systems, security, vehicle logistics and asset tracking, environmental monitoring and energy control, industrial control and smart metering.
