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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
