Maniacal Labs PiPixel
The PiPixel provides simplified hookup of digital LED strips to the Raspberry Pi family of single board computers. It uses the standard Pi "HAT" form-factor to provide two easy power input options, and data output of the SPI port as well as GPIO 18 and 13 (used for WS2812), along with built-in voltage level shifting to keep your LED strips happy being connected to the 3.3V Pi. No longer will you have a rats-nest of wires and power between your Pi and your LEDs. Slap on the PiPixel, connect power, connect LEDs, and go!
What's In The Bag
Your PiPixel is a user assembled kit which only requires basic soldering skills and comes with the following components:
- PiPixel PCB
- Female 2x20 Header for connection to Pi
- 2.1 / 5.5 mm barrel jack for power input option #1
- 5mm pitch dual screw terminal for power input option #2
- 74AHCT125 Level Shifter
- 4 pin screw terminal for data/power output
- 2x3 pin header and jumper for data line selection
Where To Get Optional Headers
We ship the PiPixel with a standard 2x20 Female header as that's what most users are likely to use. But it supports a few other options which we don't currently provide. See the list below for links of where to buy those, should you need them.

Questions
How big is the PiPixel PCB?
It measures 65 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PiPixel use?
13 parts, built around the 74AHC125D. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the PiPixel KiCad files?
From the ManiacalLabs/PiPixel repository on GitHub, at the commit this page was made from: the board is PCB/PiPixel.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the PiPixel design in my own project?
Its repository states no licence, so its author keeps all rights: ask ManiacalLabs before reusing the design.
