What is Pixeldust?
This is a brand new (in development) YSWS where you design your own neopixel-based PCB trinket, and we'll ship it to you for free! Make sure to join #pixeldust in the slack so you dont miss out!!
You ship...
- A PCB design for the board
- Working firmware to control the neopixels
We ship...
-
1 fully assembled PCB
- This will include your XIAO RP2040 as well as the neopixels
-
2 unassembled PCBs
Requirements
- Your firmware must be working!!! We won't approve any without.
- It must be more complex than just a simple blinking LED
- Your PCB cannot exceed 100cm^2
- Your PCB must only use 2 layers

Questions
How big is the ProximityGradient PCB?
It measures 76.2 × 63.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ProximityGradient use?
70 parts, built around the WS2812B. 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 ProximityGradient KiCad files?
From the hackclub/pixeldust repository on GitHub, at the commit this page was made from: the board is submissions/ProximityGradient/ProximityGradient.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the ProximityGradient design in my own project?
Its repository states no licence, so its author keeps all rights: ask hackclub before reusing the design.
