LG02 Dual Channels LoRa IoT Gateway

LG02 is an open source dual channels LoRa Gateway. It lets you bridge LoRa wireless network to an IP network via WiFi, Ethernet, Or 3G/4G cellular via optional LTE module. The
LoRa wireless allows users to send data and reach extremely long ranges at low data-rates. It provides ultra-long range spread spectrum communication and high interference immunity.

LG02 has Rich Internet Connection method such as WiFi interface, Ethernet port and USB host port. These Interfaces provide flexible methods for users to connect their sensor networks to Internet.

The design of LG02 is use the Linux to directly control two sx1276/sx1278 LoRa modules which lets the LoRa can works in full duplex LoRa mode and increase the communication efficiency.

LG02 can be used to provide a low cost IoT wireless solution to support 50~300 sensor nodes.

LG02 can support mutiply working mode  such as: LoRa repeater mode, MQTT mode, TCP/IP Client mode, TCP/IP Server mode to fit different requirement for IoT connection. Click this link for more info about the modes.

Note: LG02 is designed for Private LoRa Protocol, Not recommend for LoRaWAN use.
