Description

XTR-8LR10 is a half duplex transceiver for long range radio communications based on a patented "LoRa SSM" modulation technique, which provides high interference immunity, high sensitivity and very low power consumption with + 14dBm of power .

Compared to standard modulation techniques, the XTR-8LR10 improves receiver sensitivity by up to 20dB, allowing long distances using low transmit power and low power consumption, cheap power circuits and low cost batteries.

The transceiver works in 868 ÷ 868.6MHz (25mW ver. 8LR10), 869.4 ÷ 869.65MHz (25mW, ver. 8LR10), 869.70 ÷ 870.00MHz (25mW, ver. 8LR10) European band with the possibility of set the width of the channel. XTR-8LR10 is a radio-modem with UART input interface, working on data packets (max size 255 bytes).

It can manage addressing schemes for point-to-multipoint star networks. The main radio parameters can be set without problems via the command mode procedure, which offers the user flexibility and multiple solutions to the numerous problems involved in the field.

The operating voltage is 3.3V, the current consumption is 17 mA in reception and 30 mA in transmission (14 dBm ERP).

The module is available in SMD version, for surface and vertical mounting, 18 pins whose dimension is 33.5 X 15.4 X 2.4 mm.
