G60

Product relationship

G60 is a keyboard product supporting two wireless backends: legacy BLE firmware (Bluefruit) and AVR DuoChord (same PCB, pick one).

Quick identification

• Product name: G60.
• MCU: ATmega32U4.
• Layout: 60% (ANSI / ISO multi-layout, including arrow variants).
• Wireless backend: Bluefruit or DuoChord.
• Flashing: .hex + qmk-dfu.

Do-not-mix warning

• G60 Bluefruit and DuoChord firmware are not interchangeable.
• Migrating from Bluefruit to DuoChord requires a fixed sequence, see first migration.
• Do not flash firmware from other models (Manta, F60, Command65, etc.).

Recommended firmware download

Firmware, VIA JSON definitions, and SHA-256 checksums are available in the Download Center (see Firmware Downloads). DuoChord targets also need a matching nRF OTA package, shipped as part of the first-migration kit.

First use / migration prerequisites

• Legacy BLE firmware (Bluefruit): download the matching legacy BLE firmware for G60, flash it, then pair following Legacy BLE firmware.
• DuoChord: if the module currently runs Bluefruit, flash the AVR DuoChord firmware first, then hold both Shift keys and press F twice to enter DfuTarg, perform OTA, and re-pair. See Legacy BLE firmware → DuoChord first migration.
• Flashing methods: see Wired Flashing (DFU / TinyUF2).

Common features

• Legacy BLE firmware operations: see Legacy BLE firmware.
• DuoChord operations: see AVR DuoChord.
• PCB identification: see Identify Your Keyboard & PCB.

Default keymap

The default keymap provides a 60% layout. Wireless function keys (BLE1–BLE5, PAIR, CLR, etc.) follow the firmware you flash.

Model-specific features

• 60% multi-layout (including arrow variants).
• Bluefruit / DuoChord dual wireless backends.

Troubleshooting

• Cannot connect wirelessly: see Troubleshooting / Wireless.
• Stuck keys (legacy BLE firmware): see the Legacy BLE firmware limits.
• Stuck mid-migration: see the first migration.

Version compatibility

• Hardware revision: G60 (only).
• Config tools: VIA / Vial.
• Firmware: QMK / Vial builds for the G60 target; DuoChord targets also need the matching nRF OTA package.
