Hardware Description - 1gate/1G-LWG-COM-868-XXX GitHub Wiki
1GATE LoRaWAN Compact Gateway is build around a Raspberry Pi 3 embedded computer and a proprietary RPI HAT LoRa Concentror. Our LoRa concentrator use the Semtech SX1301 digital baseband chip and two Semtech SX1257 RF Front-end transceiver.
GNSS connectivity (u-blox MAX-M8Q) is available as an option.
