Sinc Hotswap Build Guide

ISO Enter Support Conversion: To convert the board to support ISO Enter, you'll need to desolder/resolder two of the hotswap sockets. See the build guide for additional details.

This keyboard uses the popular open-source QMK Firmware with VIA enabled out of the box to allow you to remap all the keys just the way you want them.

Plug your keyboard in, open up the VIA app, and easily change what each key does to get the most out of your keyboard with your customizations! More info on what you can do here: VIA Usage Guide

Rev. 4 vs. Rev. 3 PCBs:

  • Added VBUS circuit for more reliable keyboard startup of each half when booting or waking up your computer
  • Added a couple more layout options at thumb keys on the bottom row

Great board for gaming

I love my sinc so much for gaming. Most of the day i keep both halves out, but I can stash away the right half and get back so much mouse room it's insane. Plus the macros are useful for artisan displaying. Wonderfully board

Love my Sinc(s)

I've built three of these now in assorted generations of PCB and they are all great. I love the rotary dials and the full-sized split board (I can't lose my function keys). If you made an Ortho linear version I'd probably end up with 3 of those too.

Great board, great customer service

The board was easy to build with the instructions on the Keebio YouTube channel, and customer support was very fast and helpful when I accidentally bought the wrong plate for the PCB I ordered.

Fantastic Board

Have been loving my Sinc for the past week or so. Fairly easy to build and looks great. I'm planning on trying it with a 3d printed case, but I've been loving the bare look to the point I don't know if I'm going to use it in the long run. (Boba u4t switches; Drop + Matt3o MT3 Susuwatari keycaps; DEADLINE studio - DOYS for macros keys)
