Product Description

The MMkeyboard MMClass80 is a full-size mechanical keyboard designed for users who want a solid, retro-inspired typing experience with flexible connectivity. It suits hobbyists who value a heavy, sturdy build and multiple mounting options, as well as those who want both wired and Bluetooth use with customizable firmware. It is less ideal for users seeking a compact or lightweight keyboard.

Key Features

  • Hot-swap and soldered PCB options allow easy switch replacement or permanent builds.
  • Supports ANSI and ISO layouts, with 6.25U or 7U spacebar compatibility depending on PCB type.
  • Includes a 7° typing angle for ergonomic hand positioning.
  • Optional retro-style keycaps available separately, matching popular color profiles.
  • Wired PCBs support QMK and VIA firmware for extensive customization; Bluetooth uses Dana’s LDN software.

Build Quality and Mounting

  • Heavy aluminum case weighing about 3.5kg, providing stability during typing.
  • Supports three mounting styles: top mount with plate, gasket mount with plate, and gasket mount plateless, affecting typing feel and sound.
  • Standard kit includes a PC plate with PCB-mounted stabilizers; additional plates in various materials can be purchased separately.
  • Includes multiple foam layers inside the case to reduce noise and vibration.
  • Comes with a stainless steel "Class80" badge and a carrying case sized for its large footprint.

Typing Experience

  • Leaf-spring mount on the PCB offers a soft, cushioned keypress similar to the MMClass65.
  • Multiple foam layers and gasket mounting options help control acoustics and typing noise.
  • PCB-mounted stabilizers standard, which may affect stabilizer feel compared to plate-mounted versions.

Connectivity

  • Available in wired and Bluetooth versions; wired supports both hot-swap and soldered PCBs.
  • Bluetooth version only supports hot-swap PCB and includes a 5000mAh battery for wireless use.
  • Bluetooth PCB does not support buzzer or solenoid sound modules included with wired kits.

Trade-offs

  • Large size and weight make it less portable despite included carrying case.
  • Bluetooth version lacks buzzer and solenoid features, reducing sound feedback options.
  • Brass plates may interfere with Bluetooth signal, limiting material choices for wireless users.
  • Keycaps are not included and must be purchased separately if desired.
