Product information "Adafruit RFM95W LoRa Radio Transceiver Breakout, 868 or 915 MHz"

Sending data over long distances is like magic, and now you can be a wizard with this range of powerful and easy-to-use wireless modules. Sure, sometimes you want to talk to a computer (a good time to use WiFi) or maybe communicate with a phone (choose Bluetooth Low Energy!), but what if you want to send data very far? Most WiFi, Bluetooth, Zigbee and other wireless chipsets use 2.4 GHz, which is great for high-speed transmissions. If you're not so concerned with streaming video, you can use a lower licence-free frequency such as 433 or 900 MHz. You can send data not as fast, but much further.'

Also, these packet radios are simpler than WiFi or BLE, you don't have to associate, pair, scan or worry about connections. All you do is send data whenever you want, and any other module tuned to the same frequency (and with the same encryption key) will receive. The receiver can then send back a reply. The modules do packetisation, error correction and can also auto-retransmit, so it's not like you have to worry about everything, but less energy is wasted on maintaining a connection or pairing.

These modules are great for use with Arduinos or other microcontrollers, say if you want to rework a sensor node or transmit data across a campus or city. The downside is that you need two or more radios with matching frequencies. WiFi and BT, on the other hand, are often included in computers and phones.

These radio modules come in four flavours (two modulation types and two frequencies) The RFM69's are the easiest to use, and are well known and understood. The LoRa radios are more exciting and powerful, but also more expensive.

This is the 900MHz radio version which can be used for either 868MHz or 915MHz transmit/receive - the exact radio frequency is set when loading the software as it can be dynamically retuned. We also stock a 433MHz version. These are +20dBm LoRa packet radios that have a special radio modulation that is not compatible with the RFM69s but can go much further. You can easily go 2km line of sight with simple wire antennas, or up to 20km with directional antennas and tweak settings

Packet radio with ready-to-use Arduino libraries
Uses the licence-free ISM band: "European ISM" @ 868MHz or "American ISM" @ 915MHz
Uses a simple wire antenna or a spot for uFL or SMA radio connectors
SX1276 LoRa® based module with SPI interface
+5 to +20 dBm up to 100 mW output power (output power selectable in software)
~100mA peak with +20dBm transmission, ~30mA with active radio listening.
Range of approx. 2km, depending on obstacles, frequency, antenna and output power

All radios are sold individually and can only talk to radios of the same part number. E.g. RFM69 900 MHz can only talk to RFM69 900 MHz, LoRa 433 MHz can only talk to LoRa 433, etc.

Each radio comes with some headers, a 3.3V voltage regulator and level shifter that can handle 3-5V DC voltage and logic, so you can use it with 3V or 5V devices. Some soldering is required to attach the header. You will need to cut and solder a small piece of wire (any solid or stranded wire is fine) to create your antenna. Optionally, you can take a uFL or SMA edge connector and attach an external antenna.

This is the 900 MHz radio version that can be used for either 868MHz or 915MHz transmit/receive

- the exact radio frequency is determined when loading the software as it can be retuned dynamically

Adafruit: The expert for open source hardware

For more than ten years, programmers and tinkerers have benefited from the expertise of the Adafruit brand. Whether for beginners or proven experts, Adafruit has the right hardware components ready for your next IoT project.

Light comes into the dark with Adafruit NeoPixel

One extremely popular product line from the company's broad portfolio is Adafruit NeoPixel. These nifty LED components come in a wide variety of designs and color temperatures. NeoPixel modules are available, for example, in the form of a practical stick with five intelligent LEDs in red, green and blue (RGB) or in white (W), as a shield with 40 eye-saving RGBW LEDs in which all pixels are individually addressable, and as a jewel with seven RGBW LEDs that can be controlled with 8-bit PWM per channel.

Especially popular is the Adafruit NeoPixel Ring with 16 ultra-bright, intelligent RGB LEDs including integrated drivers, which you only need a single microcontroller to control. The trick is that the Adafruit NeoPixel rings form a chain, so to speak: You couple the output pin of one with the input pin of the other.

With the Adafruit NeoPixel products you can realize a wide variety of projects - there are virtually no limits to your creativity. With the help of an Arduino, a jumper cable and the appropriate software, you can control a NeoPixel ring individually and light up the small LEDs as you wish - either individually or in a specific combination. This way, you can also create your own Vu meter with the versatile LED components. Practical: To make programming Adafruit NeoPixel easier, Adafruit provides an Arduino library as well as a Python library.

Adafruit Feather Boards: Powerful hardware in a compact format

With Adafruit Feather, the hardware specialist from the States also has various powerful development boards in its range, which are essentially equivalent to an Arduino in terms of function. All of these boards are equipped with similar features; among other things, the pin assignment is the same and there are also many parallels when it comes to the microcontrollers and the battery charging properties. In addition, you can also find Feather boards with special devices like Bluetooth, Wi-Fi and cellular network connectivity as well as boards with microSD slot in Adafruit's product range. The name "Feather" is no coincidence: The boards are also characterized by being particularly compact and, above all, lightweight.

The range of top-class product highlights is wide: The STM32F405 Feather, for example, is the fastest CircuitPython board from Adafruit with an outstanding 168 MHz and meets the highest demands. It is equipped with a STEMMA QT / Qwiic port at the end, which makes it easy to connect to I2C sensors. The Adafruit Feather nRF52840 Express, on the other hand, shines with Bluetooth Low Energy and can also be used with CircuitPython thanks to native USB support.

Another important part of Adafruit's portfolio are the FeatherWings. With these expansion modules, you can also include components such as a display or a motor driver in your IoT project. The FeatherWing Proto is a proven classic in Adafruit's portfolio. This is ideally suited as a prototyping add-on for all Feather boards. The Adafruit FeatherWing Wing Tripler Mini Kit, on the other hand, is ideal if you want to connect a Feather to two other FeatherWings at the same time.

With the Adafruit MIDI FeatherWing Kit you get a music capable FeatherWing, thanks to which you can equip your Feather with MIDI input and output jacks. And with the Adafruit FeatherWing OLED you can easily add a small OLED display to your Feather board - no soldering required.

Adafruit: What's behind the brand

As an expert in open-source hardware, Adafruit has long since established itself in the electronics industry. The company was founded in 2005 by Limor Fried. At the time, the talented and innovative electrical engineer was still a student at the renowned Massachusetts Institute of Technology (MIT). To this day, Fried is CEO of the electronics giant, which is now headquartered in New York. The company's name also goes back to its founder: Fried was once known on the World Wide Web by the nickname "Ladyada" - a tribute to the famous IT pioneer Ada Lovelace.

Adafruit says it is committed to getting more people excited about technology and science - and thanks to its first-class products, the hardware expert from the USA is sure to succeed!
