tRF click is an add-on board in mikroBUS form factor. It can be used to wirelessly send and receive UART data. It features the Telit LE70-868 - 868 MHz transceiver module with an embedded stack that is easy to integrate and use in point-to-point or star network topologies. The click also carries an SMA connector for an antenna as well as two radio communication LEDs. It enables radio data rates from 4.8 to 57.6 kbps with maximum output power of 500mW and a range of up to 10km in ideal conditions (open space). We managed to get a good 4km range in mixed conditions. The board is designed to use 3.3V power supply only. A LED diode serves as a power indicator. Note: Antenna sold separately.
