Product Description: Pixel Shifter - 3.3V/5V Logic Level Converter for Addressable LEDs - Adafruit 6066
The Adafruit Pixel Shifter is designed to work with addressable LEDs such as the WS2811, WS2812, NeoPixel, SK6812 , and compatible solutions requiring 5V logic signals. The module eliminates problems associated with unstable operation of LED strips controlled directly by microcontrollers using 3.3V logic. The board includes a 5V step-up circuit , two signal buffers, and a signal inverter, allowing it to support both standard and less common LED drivers .
Pixel Shifter - 3.3V/5V logic level converter for addressable LEDs - Adafruit 6066.
The module is powered by a voltage of 3 V to 5 V and consumes only a few milliamps of current.
Adafruit Pixel Shifter Key Features
- Logic Level Conversion : Convert 3.3V signals to 5V signals for addressable LEDs
- Two signal channels : data and clock line support
- Inverted output : dedicated to systems requiring an inverted signal, e.g. TM1814
- Built-in 5V voltage generator : power supply for the conversion system without additional components
- 74HCT2G34 chip : supports signals with frequencies up to 10 MHz
- NeoPixel and DotStar compatibility : support for single and dual wire LEDs
- Built-in NeoPixel diode : quick diagnostics of the correctness of the data signal
- Screw connectors : easy wire connection without soldering
- Low power consumption : 3V to 5V power supply with a power consumption of just a few milliamps
Pinouts and compatibility
The module features convenient 2.54 mm pitch screw connectors . The input side features V (power), G (ground), DAT (data line), and CLK (clock line) pins. The output side provides D5 (5 V data), !D5 (5 V inverted data), and C5 (5 V clock) signals. This allows the module to work with both LED strips using a single data line and solutions requiring an additional clock signal. Pixel Shifter is designed for microcontrollers using 3.3 V logic . The module is compatible with RP2040, ESP32, ESP8266, STM32, SAMD, Raspberry Pi , and many other platforms equipped with digital outputs. It is compatible with popular addressable NeoPixel, WS2812B, WS2811, SK6812, DotStar (SK9822) LEDs and drivers requiring an inverted signal such as the TM1814 .
The Adafruit Pixel Shifter is designed to work with addressable LEDs such as the WS2811, WS2812, SK6812, and other compatible solutions.
Programming and cooperation with WLED
The module requires no proprietary software and operates as a hardware signal converter. It can be used with the Adafruit NeoPixel, FastLED, CircuitPython NeoPixel, and other addressable LED lighting control libraries . Pixel Shifter also works well in WLED -based projects, providing correct logic levels for LED strips controlled by an ESP32 or ESP8266.
