New design copy

This repository is to show people my attempt to build a hackpad of my own. As of now I don't know how it will turn out but I hope its good

Schematics

# Note The bottom one and the little rectangle will be printed with transparent PLA. To give it an underglow effect and make a window for the microcontrollers I have the screws thats why i didnt include it in the BOM. ## Details This hackpad is made to help me have a better time while programming, gaming and 3D printing things. ### BOM - 9 Cherry MX Switches - 12 SK6812 MINI LEDs - 1 XIAO RP2040 - 9 Blank DSA Keycaps - ~ 80g Normal PLA - ~ 30g transparent PLA Disclaimer: The switches and the top part fits perfectly because of some issues on my macbook I can't upload the video/image onto my github repo so if you have any questions please contact me via slack so that I can show you how it is made myself and answer any questions ### My request for the staff: Please don't require a full component assembled photo/file as it is way too much work that I need to remove all the stuff to print it and it didn't make a difference in the aligning part as well cause i just had to flip the top part and that's it.

Questions

How big is the New design copy PCB?

It measures 64.2 × 82.7 mm and has 2 copper layers, 1.6 mm thick.

What parts does the New design copy use?

33 parts, built around the SK6812MINI-E. 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 New design copy KiCad files?

From the ELF123blahblah/Split-Keyboard repository on GitHub, at the commit this page was made from: the board is Hackpad's PCB/New design copy.kicad_pcb and its schematic Hackpad's PCB/New design copy.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the New design copy design in my own project?

Its repository states no licence, so its author keeps all rights: ask ELF123blahblah before reusing the design.
