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.
