If you’re building a IoT project and need to send data back-and-forth, the WiFi module built into newer Pi’s should be fine for most cases. But, what if you find WiFi does not have a long range you need? If you’re deploying your project somewhere more remotely, without WiFi or a strong cellular network, like a rural area, you’ll need another option. Something that can be deployed quickly with no overhead setup and that will transmit/receive over a long distance.
Enter LoRa (Long Range) Radio — a smart, long-range, wireless transmission technology that enables the future of IoT (Internet of Things)without Cellular fees.
This LoRa HAT from RAK Wireless is capable of multi-channel, multi-node communication all running in a non-intimidating, hackable Raspberry Pi environment. Unlike our basic LoRa gateway bonnet, this chipset can support all 8 channels, so it can handle multiple clients, on different LoRa channels, without having to do any code tweaks.
We’ve pulled together a pack with all the hardware you need to make a Raspberry Pi Powered LoRa router! Some assembly is required to screw together the parts, but no soldering is required. You even get an SD card ready to rock.
- Raspberry Pi 3 B+
- 5V 2.5A Switching Power Supply with 20AWG MicroUSB Cable
- 915MHz 8-Channel LoRa concentrator + GPS shield
- 16GB MicroSD card ready to pop into your Raspberry Pi
- Magnetic mount GPS/GNSS antenna 1m with SMA connector
- 915 MHz LoRa compatible antenna (2dBi Gain / 50 Ω)
- Mounting kit with 4 x brass standoffs & 4 x washers
- Sleek and compact anodized enclosure (3 pieces): 68.3 mm x 92 mm x 53.5 mm
- 8 x 10mm tall screws
- 4 x 4.75mm tall screws
- 4 x Rubber stoppers
Once you have your Internet-to-LoRa gateway set up with this kit, make LoRa nodes using our Feather line for easy deployment of sensor networks that run on battery power. Don’t forge to only use 900 MHz LoRa modules to match up with this transceiver HAT’s frequency.
