Description
Product information "Adafruit LoRa Radio Bonnet with OLED - RFM95W @ 915MHz"
Not only do you get a wireless module, but also a 128x32 OLED display for status messages and three buttons that allow you to create your own user interface or send test messages. All of this is supported by our Python libraries, so that you can send or receive LoRa data with other suitable modules, send data to a LoRaWAN gateway or even set up your own single-channel LoRaWAN-to-Internet gateways.
Compared to the 2.4 GHz WiFi/Bluetooth radios already on the Pi, these modules run on 433 or 900 MHz (sub-GHz). They can send data not as fast, but much further. 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 all other modules, tuned to the same frequency (and with the same encryption key), will receive it. The receiver can then send back a response. The modules take care of packetisation, error correction and can also re-transmit automatically, so you don't have to worry about everything, but less energy is wasted on maintaining a connection or pairing.
These modules are ideal for use with other microcontrollers with matching radios (such as RadioFruit Feathers), e.g. if you want to create a sensor node.For example, if you want to set up a sensor node network or transmit data across a campus or city. The disadvantage is that you need two or more radios with matching frequencies.
These radio modules come in four variants (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 900 MHz LoRa radio version that 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. 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 achieve 2km line of sight with simple wire antennas, or up to 20km with directional antennas and the right settings.
- Packet radio with ready-to-use CircuitPython 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
Each Bonnet is supplied fully assembled and ready to use. You can attach an antenna via the uFL connector or cut and solder a small piece of wire (any solid or stranded core is fine) to create your antenna.

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!
