Dragino OLG01 Outdoor Single Channel LoRa Gateway Runs OpenWrt, Supports Passive PoE

Dragino Technology, a Shenzhen based startup focusing on the Internet of Things, had already designed LoRa shields & Hats for Arduino & Raspberry Pi boards which can be useful for LoRa nodes, but the company has now launched Dragino OLG01 LoRa gateway running OpenWrt that communicates with nodes over LoRa, and to the cloud using WiFi, Ethernet, or 3G/4G.

Dragino OLG01 specifications:

  • WiSoC – Atheros AR9331 MIPS processor @ 400MHz
  • System Memory – 64MB RAM
  • Storage – 16MB flash
  • MCU – Atmel ATMega328P AVR MCU with 32KB flash, 2KB SRAM
  • Connectivity
    • 802.11 b/g/n WiFi with antenna
    • 2x 10/100M Ethernet with support for passive PoE
    • Optional 3G/4G module connected to internal USB socket (TBC)
    • Semtech SX1276/78 LoRa wireless module + SMA connector (antenna not provided) up to 5~10 km range
  • USB – 1x USB 2.0 host port
  • Power Supply – 12V DC power jack or PoE

Three models are offered with 433, 868, or 915 MHz frequencies: OLG01 433, OLG01 868, and OLG01 915. The weatherproof gateway is designed to be wall mounted, and ships with a 12V power supply, and a PoE injector. OLG01 runs OpenWrt, and documentation can be found on Dragino Wiki, source code on Dragino Github account. The gateways supports auto-provisioning, network firmware update, includes a web server and management UI. The Atmel MCU can be programmed using the Arduino IDE. Note that most of the documentation refers to LG01 instead of OLG01, but both gateways appears to be based upon the same hardware, except OLG01 is weather-proof, and suitable for outdoor use.

Potential application include wireless alarm and security systems, home and building automation, automated meter reading, industrial monitoring and control, long range irrigation systems, GPS tracker,etc… some of which are described in Dragino video below.

You’ll also find some more information on the product page, including a datasheet and a detailed user manual. Dragino OLG01 can be purchased for $70 on Tindie. If you don’t need PoE, nor a weatherproof case, LG01 gateway will be cheaper at $56.
