Zest_Module_LoRa868
Overview
The Zest_Module_LoRa868 is an electronics development board for 6TRON open source platform based on Semtech SX1262IMLTRT component.
The SX1262IMLTRT is a LoRa RF transceiver for the frequencies range between 150MHz to 960MHz. It is customized to work at 868MHz and can transmit up to +22 dBm with highly efficient integrated power amplifier.
The board is equipped with an U.FL connector to plug an external antenna.
The module must be embedded on a Zest_Radio_LoRa868 daughter board to interface the 6TRON bus. It can be used directly on customer’s proprietary mother board.
The Zest_Module_LoRa868 module offers 6TRON users a Long-Range connectivity to devices, systems and sensors communicating with low power over a long distance.
