Build Guide 


This is the pre installed keymap for the Plaid-Pad.
You can find more informations on the QMK Firmware Keymap site.

The USB-C connector is a bit difficult to solder. I can do it for you.
 "Soldering service for USB-C connector"



  • Top, mid and bottom pcb (choose color)
  • 2mm clear acrylic guard plate (has bluish protection film)
  • Solder parts with pre flashed Atmega328 (USBaspLoader and QMK firmware with VIA support)
  • Spacer and screws (white kit: stainless steel with T6 Torx, black kit: brass slotted screws)
  • Rubber feeds

With the software "Plaid Pad MIDI" (by Mitchell van Manen), you can use the Plaid-Pad as a Midi device.

Great build for beginners

This was a perfect level for a first build. Not too difficult but still challenging enough to make you feel more comfortable with soldering. Like stated above make sure that you have 5-pin switches since there isn't a top plate.
Ben has been awesome throughout this whole time. Any questions I had he was very responsive and very helpful. Great products, great seller!

Very enjoyable first build. the guide helps not to feel too lost

I really enjoyed the build. Everything is pretty well labeled, or if it's not labeled, then there is no confusion (thinking about the Zhener diodes, that are not labeled but only have the symbol)

The wiki page guides you well, but I felt a bit lost when I reached the switch soldering.
All my switches only had 3 "prongs" (feet?) and as a result, the keys are a bit wonky and not that well aligned.
I suppose that's why there are switches with 5 prongs, to keep them well aligned.
I am not complaining that it's not indicated on the shop page, but a simple "recommended" link to switches could have cleared the case, especially for a beginner.

Also, the USB C gave me some difficulties, but bad eyesight and shaky hands didn't helped.
I would have liked the option to use a full Arduino with an already soldered USB port.
My usual soldering iron (ts100) was way to wide to solder that... I had to find an iron with a smaller tip, and I was unsure if I had a short circuit, but as I could not remove it, I tried to power the keypad and it was ok.
So, it looks like there are traces between the left and right most pins to the ground.

I am now looking how to flash a custom qmk firmware, as I want to have a second layer and some macros available.
I still haven't found how, that's unfortunate that the wiki doesn't cover that part.
It's like the reset / boot button. Reset I understand, but what purpose the boot button have?
It's a mystery for me.
