Adafruit Pixel Shifter - For Addressable LEDs
The Adafruit Pixel Shifter was developed to solve voltage and signal problems when using addressable LED strips with 3.3V logic systems such as Raspberry Pi, ESP32, or STM32. As many LED strips expect a 5V control signal, signal problems can occur when directly controlled by 3.3V logic levels. The pixel shifter compensates for these differences by amplifying the signal and inverting it if necessary.

The module has two signal outputs for this purpose, which enable flexible control of addressable LED strips. One of the outputs forwards the signal unchanged, while the other generates an inverted version of the same signal. This inversion means that a "HIGH" signal (logic 1) becomes a "LOW" signal (logic 0) and vice versa. This allows the module to work with LED strips that expect a normal 5V signal as well as those that require an inverted control signal. The signal output is always at a stabilised level, which reduces signal interference and improves compatibility with microcontrollers.

The 74HCT2G34 (a fast logic module for signal amplification) forms the heart of the module and supports signal frequencies of up to 10 MHz - significantly more than the typical 800 kHz of LED strips. Wiring is via 0.1" terminal blocks that are compatible with cables from 18AWG to 26AWG (wire gauges for different current loads). An integrated NeoPixel diode (an individually addressable RGB LED) is used for signal analysis and can be deactivated by disconnecting a back connection.

This compact and lightweight module (25.5mm × 15.0mm × 10.2mm, 3.5g) offers an uncomplicated solution for the use of LED strips with modern microcontrollers and can also be used as a debugging tool. It is particularly suitable for projects with WLED (open source software for LED control) or other LED-based applications.

Choosing the right power supply is crucial, as addressable LEDs have high power requirements. A WS2812B LED strip requires around 60 milliamps per LED at full brightness in the colour white. The current requirement increases with the number of LEDs, so that a strip with 30 LEDs requires around 1.8 amps, a strip with 60 LEDs around 3.6 amps and a strip with 144 LEDs around 8.6 amps. As neither the microcontroller nor the pixel shifter can supply sufficient current for larger LED strips, it is recommended to use a separate five-volt power supply with sufficient amperage. The power supply unit should also be connected directly to the LED strip, as cables that are too thin or insufficient power can lead to flickering or instability. Another important point is to connect the common ground of the power supply unit to the ground of the microcontroller in order to avoid interference in the signal transmission.

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!

Safety instructions

Ensure that the operating voltage (5V) is maintained to prevent damage.
Do not expose to direct water or high humidity - electronics are not waterproof.
Avoid short circuits through correct insulation and cabling.
Take care when soldering to prevent overheating and damage to the LEDs.
Do not point LEDs directly into the eyes, as they can be very bright.
Ensure that the power supply is sufficiently dimensioned for all installed LEDs.
Only use cables specified for voltages and currents to prevent overheating or fires.
In the event of damage to the module or defective LEDs, switch off the power supply immediately.
Dispose of in accordance with local guidelines for electronic waste, as components may contain potentially harmful substances.
Keep children away from these modules as they contain small parts and there is a risk of swallowing.
