Build Guide

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 as shown below. See the build guide for additional details.

  • MX Hotswap sockets
  • Option for rotary encoders at top-left and top-right corners (non-hotswappable)
  • ANSI support - Enter area can be converted to support ISO Enter by relocating 2 hotswap sockets (We do provide a service option for this conversion), see Build Guide section below
  • Options for split ISO left shift, split backspace, and split right shift
  • Layouts supported: KLE link
  • Macro section on left half can optionally be broken off
  • In-switch RGB LEDs pre-installed
  • USB-C port
  • Compatible with MX-style switches only
  • QMK compatible, pre-flashed with VIA support for easy remapping of keys
  • Comes with left half PCB and right half PCB
  • RP2040 MCU integrated on-board
  • Per-key RGB LEDs for each switch
  • 8 RGB underglow LEDs on each half
