tRF Click Board
The tRF Click Board™ is an RF communication board featuring the Telit LE70-868 wireless transceiver module. Along with the LE70-868 short range module, the board incorporates an SMA connector for an antenna, two radio communication LEDs, and a MikroBUS connector. Telit LE70-868 is an 868 MHz transceiver module with an embedded stack that is easy to integrate and use in point-to-point or star network topologies.
tRF Click Board™ enables radio data rates from 4.8 to 57.6 kbps with maximum output power of 500mW, and features a wireless range of up to 10km in line-of-sight. However, this is the case for ideal conditions with no barriers to disrupt the signal. The user can still achieve a range of over 4km in open space under mixed conditions.
The tRF Click Board™ also includes two radio LEDS: transmit (red) and receive (yellow). It uses MikroBUS UART (Rx, Tx), AN, RST, PWM and INT lines for communication with the target board MCU. tRF Click Board™ is intended to use a 3.3V power supply only.

IC/Module: Telit LE70-868 transceiver module
Telit LE70-868 is designed to operate in the 868 MHz ISM license free frequency bands and works on very low power consumption, which makes this transceiver module an ideal solution or designing point-to-point or star networks in applications like energy monitoring, weather-stations, irrigation, etc.
The embedded stack in the LE70-868 transceiver module is easy to integrate and use in point-to-point or star network topologies.
Range of up to 10km in Ideal Conditions
tRF Click is designed to provide a range of up to 10km in open space, under ideal conditions with no obstacles to interrupt the signal. However, such conditions happen rarely. After certain casual, not-so-scientific tests, Telit LE70-868 module is found to get a range of nearly 4km.
