Product description

Telit LE modules family are the latest generation of multiband multi-channel radio module with advanced proprietary embedded stack easy to integrate and use in point-to point or star network communication.

LE70-915 modules operate in 915MHz band with 500 mW Output power and with ultra-low power standby mode, efficient wake up on radio and budget link of 142 dB.

Available in LGA format, these pre-certified RF modules provide TTL RS232 interface, integrated digital and analog I/Os and can be easily integrated into applications such as energy monitoring (windmills and solar panels), weather stations, irrigation, and watering, thus reducing development time and cost while providing highly reliable communications .

LE70-915 modules have the same form factor and pinout of LE50-868 and LE70-868. They have also the same form factor and are pin to pin compatible with Telit ZE Family (ZigBee 2007 and PRO stack), NE Family (Mesh low power) and ME Family (Wireless M-Bus).

Key Benefits
• Superior outdoor LOS range of up to 40 miles with 6 dB antenna gain, 500 mW output power and -115 dBm @ 9.6 Kbps sensitivity
• 902-928 MHz band with Frequency Hopping Spread Spectrum on 50 channels aligned with FCC regulation
• Ready to use and easy to handle (suitable for cable replacement applications) with Data encryption (AES128) available, Cyclic wake up and Download Over The Air (DOTA) features
