$20, comes with radio transceiver Adafruit Feather RP2040 RFM69 Packet Radio - 868 or 915MHz Lipoly battery and USB cable are not included, but we do have lots of options in the shop if you'd like!
This is the Adafruit Feather RP2040 RFM69 Packet Radio (868 or 915 MHz). We call these RadioFruits, our take on an microcontroller with packet radio transceiver with built-in USB and battery charging. It's an Adafruit Feather RP2040 with a RFM69HCW 900MHz radio module cooked in! Great for making wireless networks that are more flexible than Bluetooth® LE and without the high power requirements of WiFi.
It's kinda like we took our RP2040 Feather and RFM69 900MHz breakout board and glued them together. You get all the pins for use on the Feather, the Lipoly battery support, USB C power / data, onboard NeoPixel, 8MB of FLASH for storing code and files, and then with the 8 unused pins, we wired up all the DIO pins on the RFM module. There's even room left over for a STEMMA QT connector an a uFL connector for connecting larger antennas.
This is the 900 MHz RFM69 packet radio version, which can be used for either 868MHz or 915MHz transmission/reception - the exact radio frequency is determined when you load the software since it can be tuned around dynamically. Despite calling it a 'packet' radio (and it does send packets of data) the RFM69 can also be used for non-packetized radio transmission and reception.

Universal wireless communication library for embedded devices - jgromes/RadioLib
ese notes are for someone who has successfully created a few sketches for their Arduino based device but is starting out with LoRaWAN. You don't have to be a C++ coding ninja but some familarity with C++ and procedural programming is assumed
LoRaWAN is an amazing system for small battery powered sensors collecting data for years at a time. With great features comes some more complex elements which means it is not quite as simple as just providing WiFi credentials and pushing data through. It is in the range of setting up & customising the settings for a home router but with no wizards to do the heavy lifting for you. So we strongly recommend spending a couple of hours reviewing the TTN Getting Started section so you are aware of the minimum knowledge to make a successful start: https://www.thethingsnetwork.org/docs/lorawan/.
This sketch isn't particularly aimed at The Things Stack (TTS) but you can get a free Sandbox account and the following instructions are for that. Chirpstack works just as well, but the buttons and labels may have different names. We discourage the use of Helium as it does not support LoRaWAN v1.1 and has some other odd limitations.
t is simpler to register your gateway first. If you don't have a gateway, then a The Things Indoor Gateway (TTIG) is a very affordable option.
LoRa stands for Long Range - having the gateway & device on the same desk tends to overload both receiver circuits when they hear a transmission so close to hand. The gateway should be 5 - 10m away, preferably with a solid wall in the way as well.
Onced logged in to the console you can go in to Applications to create your first application. The ID must be all lower case or numbers, no spaces, dashes are OK and it has to be unique to the entire TTN community - so first-app will be rejected - you could use your-username-first-app
You are making your own device using a third party LoRaWAN stack so there will not be an entry in the device repository so choose 'Enter end device specifics manually'.
Choose LoRaWAN 1.1.0 - the last one in the list - the latest specfication. RadioLib uses RP002 Regional Parameters 1.0.4.
use all zero's as recommended by The LoRa Alliance TR007 Technical Recommendations document. Once you've put in all zeros and clicked confirm you will be asked for a DevEUI, AppKey and NwkKe
For development purposes however we need to turn off one of the security settings so that you can join & uplink out of the normal sequence that a device in the field would do.
Resets join nonces' option. You will see a warning about replay attacks which is entirely proper & correct
Waveshare SIM7600G-H 4G HAT (B) for Raspberry Pi Supports LTE Cat-4 4G/3G/2G GNSS Positioning Global Band
This is made to mount underneath a Raspberry Pi Zero computer, and has the same footprint as that circuit board. It comes with a pair of PCB antennas for LTE, and a GPS amplified antenna on a 10' cable. It comes with an audio jack you can plug a headset into, allowing making regular voice calls with it easy without any other components, as well as using as a data modem. I didn't want to use a Pi Zero module, so my plan is to operate this from a Pi Pico board, but for my initial tests I just connected the micro USB jack on this module to a USB port on a Dell Latitude running Linux, and also running Windows 10. The phone worked on both operating systems, connecting using Minicom in Linux and PuTTY in Windows. Waveshare's website and Wiki were very helpful, and I was able to initiate and answer voice calls, send and receive SMS text messages, and connect to the Internet through the USB port, again with both Windows 10 and Linux. WIndows required a driver, but Waveshare tells you where to download that, and Ubuntu Linux found the device without needing a driver.
