| Variant | Common Names | Software Type | Key Feature | | :--- | :--- | :--- | :--- | | V1 (Original) | TM680, LTC NB681 | Old "TM680.exe" (灰色界面) | Rotary encoder works by default | | V2 (Upgraded) | TM680 Pro, Gamakay LK67 | Gamakay Driver (彩色界面) | Per-key RGB, better macro engine | | V3 (Wireless) | TM680 Tri-Mode | "TM680 Wireless Driver" | Bluetooth/2.4G toggle in software |
⚠️ Critical: Do not use "Gamakay LK67" software on a standard LTC TM680. It will permanently lock the encoder to volume control only.
If you’ve recently purchased a LTC NB681, Gamakay LK67, or the ubiquitous TM680 (also known as the "TOM680"), you already know it’s one of the best-value 65% exploded layout mechanical keyboards on the market. It offers a rotary encoder, triple-mode connectivity (wired, 2.4G, Bluetooth), and hot-swappable switches. tm680 keyboard software
However, to unlock its true potential—remapping keys, customizing the RGB lighting, programming the knob, or setting up macros—you need the TM680 keyboard software. Unfortunately, finding the correct, safe, and fully functional software can be a nightmare due to clone variants and broken manufacturer links.
This article is your complete resource. We will cover where to download the official software, how to install it, a step-by-step guide to using every tab, troubleshooting common errors, and how to differentiate between the QMK/VIA version and the proprietary version. | Variant | Common Names | Software Type
Before downloading anything, you must identify your exact PCB version. The TM680 is an open-source case design manufactured by multiple factories. Using the wrong software will either:
Solution: The software sometimes resets the knob to "Null." Go to Tab 1 -> Click the Knob Render -> Reassign it to "Volume Up/Down." Click "Apply" or "Write to Keyboard." ⚠️ Critical: Do not use "Gamakay LK67" software
Limitation: The encoder cannot send media "Next/Prev" directly on V1. You must use a macro.
| Problem | Solution | |---------|----------| | Software doesn’t detect keyboard | Use wired USB mode. Disable Bluetooth/2.4GHz. Replug cable. Restart software as admin. | | RGB settings won’t save after closing | Save to onboard profile (Profile tab → Save to Keyboard). The driver only controls live lighting while running. | | Knob not working in wireless mode | Some TM680 revisions limit knob customization to wired mode. Update firmware (rare). | | Macros stop working after reboot | Keep the driver running in the background, or assign macros to an onboard profile. | | Software is in Chinese | Look for a “Language” dropdown (usually top-right) – may be labeled “EN” or a globe icon. Some versions are English-only. |
