Connectivity

Wired, wireless, or the best of both.

Connectivity affects desk tidiness, latency and which controller and firmware you can use. Wired (USB-C) is the simplest and has zero latency. Bluetooth is convenient and multi-device but adds a little latency. A 2.4GHz dongle gives near-wired latency for gaming. Tri-mode boards do all three. Crucially, going wireless steers your controller and firmware choices (toward nRF + ZMK).

Wired (USB-C)

Plug in and go. No batteries, no latency, no pairing — and you can use the popular QMK/VIA firmware. The simplest, most reliable option.

Bluetooth wireless

A clean desk and easy switching between laptop, tablet and phone. Slight latency (fine for typing), needs charging, and points you toward an nRF52840 controller running ZMK firmware.

2.4GHz dongle

A USB dongle giving near-wired latency — the gamer's wireless. Often combined with Bluetooth.

Tri-mode

Wired + Bluetooth + 2.4GHz in one board. The most flexible and most common on modern premium wireless kits.

The options, compared

Every choice you'll see for this decision in the builder.

Wired (USB-C)
Simplest

The simplest and most reliable choice, and it unlocks the hugely popular QMK/VIA firmware. No batteries to manage.

Pros
  • Zero latency
  • No charging ever
  • Works with QMK/VIA
Trade-offs
  • A cable on the desk
  • Tied to one device at a time
Bluetooth wireless
Tidy desk

Switch between laptop, tablet and phone with a keypress. Points you toward an nRF52840 controller and ZMK firmware.

Pros
  • No cable, tidy desk
  • Multi-device switching
  • Portable
Trade-offs
  • Needs charging
  • Slight latency
  • Steers controller/firmware choice
2.4GHz dongle
Low latency

The gamer's wireless: a small USB receiver delivers latency close to wired, without a cable to the board.

Pros
  • Near-wired latency
  • No cable to the board
  • Great for gaming
Trade-offs
  • Uses a USB port for the dongle
  • Still needs charging
Tri-mode (wired + BT + 2.4GHz)
Do everything

The most flexible option and common on modern premium wireless kits — wired when docked, Bluetooth for travel, 2.4GHz for gaming.

Pros
  • Total flexibility
  • Wired fallback always available
  • Best of every mode
Trade-offs
  • Most expensive
  • More to configure
