(Group Buy) MK65MXW 65% Wireless Mechanical Keyboard Hotswap PCB

MK65MX: the versatile 65% PCB for ISO and ANSI builds
The MK65MXW is the wireless sister PCB to the 1.6mm Non-Flex-Cut MK65MX, with identical layout flexibility, identical case compatibility, but with full tri-mode connectivity: wired via USB-C, wireless via 2.4 GHz or Bluetooth.

This makes it possible to transform virtually any compatible 65% O-ring build from a classic wired setup into a modern wireless workflow system.

Fully QMK compatible with VIA support. Designed by Quark.

Tri-mode connectivity
The MK65MXW connects three ways to flexibly adaptable to your workflow:

• USB-C wired: direct, low-latency connection
  
• 2.4 GHz wireless via receiver: wire-free with minimal latency, ideal for gaming
  
• Bluetooth: flexible for multi-device setups (tablet, laptop, smartphone)
  The battery connection runs through the included daughterboard (Unified DB C5 footprint).

Of course, the PCB can also be used without batteries! For example, you can connect a PCB via a cable and easily switch to another system wirelessly or via Bluetooth using a keyboard shortcut even if your keyboard case does not support adding batteries to it!

Layout flexibility without compromise
The MK65MXW supports both ISO and ANSI layouts on a single PCB; with extensive multi-layout options for the main areas:

• ISO + ANSI layout support, perfect for UK-ISO, DE-ISO, or US-ANSI
  
• Split Left Shift + Big ANSI Left Shift
  
• Split backspace + regular backspace
  
• Stepped Capslock
  
• 6.25U and 7U Spacebar: compatible with most common spacebar size
  

Case compatibility
In general, the MK65MXW PCB uses the same dimensions as the wired version, so it is compatible with the same keyboard cases. However, since batteries are required for a cable-free use-case (2.4GHz and Bluetooth also work with Cable), actual compatibility depends on whether there is enough space for the batteries in the case and must therefore be tested on a case-by-case basis.

Per-key RGB and modern connection
The PCB features per-key RGB LEDs: each key individually configurable. For the daughterboard connection, the MK65MXW uses a modern PicoMolex EZMate connector, more precise, smaller, and more reliable than classic JST connectors. The daughterboard additionally hosts the battery connection.

QMK with VIA and VIAL, full adaptability
The MK65MXW runs on the proven QMK firmware (firmware source code will be released) and is VIA compatible. This lets you remap every single key, record macros, and set up layers directly in the browser, without driver installation.
