How to Add Wireless Capability to a Razer Huntsman Mini (Mod A Guide)

If you love the crisp click of the Razer Huntsman Mini but wish it could break free from the desk, a wireless conversion is the perfect project. The Mod A kit gives you the parts you need, while the DIY approach lets you learn the inner workings of your keyboard. Below is a step‑by‑step walkthrough, plus tips to avoid the common hiccups.

What You’ll Need

• Razer Huntsman Mini (the original wired version)
• Mod A wireless conversion kit – includes a Bluetooth module, battery pack, and necessary cables
• Screwdriver set (tiny Phillips #00 recommended)
• Plastic pry tool or a guitar pick for case opening
• Soldering iron with fine tip (optional, some kits are plug‑and‑play)
• Isopropyl alcohol and a lint‑free cloth for cleaning contacts

Preparing the Keyboard

First, unplug the keyboard and lay it face‑up on a clean surface. The Huntsman Mini’s case is held together by four tiny screws hidden under the keycaps. Gently pop off the caps around the escape key and the two keys next to it using your pry tool. Once the caps are off, you’ll see the screws.

Remove the screws

Unscrew the four fasteners and set them aside. The top plate will lift off with a slight tug. If it resists, double‑check for any missed screws.

Disconnect the internal cable

The PCB is attached to the case by a thin ribbon cable. Use a plastic tool to lift the connector latch, then pull the cable out. Keep the latch in sight – you’ll need it to reseal the case later.

Installing the Bluetooth Module

The Mod A kit ships with a pre‑programmed Bluetooth board that fits into the exact spot where the original USB connector sat. Align the board’s pins with the PCB’s socket; they should click into place.

If your kit requires soldering, tin the pins first, then solder each connection quickly to avoid overheating the delicate circuitry. A steady hand and a well‑heated tip make the difference.

Attach the battery

The battery pack slides into the hollow left by the original USB port. Some users prefer to tape the pack with a thin double‑sided adhesive for extra stability. Make sure the contacts line up perfectly; a misaligned battery will cause intermittent power loss.

Reassembling the Keyboard

Reconnect the ribbon cable, pressing the latch back down until you hear a soft click. Replace the top plate, then screw the four fasteners back in. Finally, snap the keycaps onto their stems. It’s a good moment to give each cap a quick press to verify that the switches still register correctly.

Testing the wireless connection

• Turn on the keyboard using the power switch on the side of the battery pack.
• Enter pairing mode (usually a long press on the power button).
• On your PC or laptop, open Bluetooth settings and look for “Razer Huntsman Mini Mod A.”
• Select it and test a few keys – the tactile feel should be unchanged.

Tips and Tricks

• Check firmware – some users flash a custom firmware to unlock advanced power‑saving features.
• Keep the battery charged – a full charge lasts about 10‑12 hours of intensive typing.
• If you notice any lag, try repositioning the antenna (the tiny metal strip on the Bluetooth board) away from metal parts of the case.
• Store the screwdriver and extra screws in a small zip‑lock bag for future tweaks.

Common Pitfalls to Avoid

One frequent mistake is forcing the Bluetooth board into the socket at an angle; this can bend pins and ruin the whole mod. Take a breath, align carefully, and apply gentle pressure only.

Another gotcha is forgetting to secure the battery’s contacts with a bit of conductive tape. A loose connection often mimics a dead battery, leading to needless troubleshooting.

Enjoy the Freedom

With the conversion complete, you’ve turned a compact, wired favorite into a truly portable gaming companion. The Huntsman Mini’s optical switches remain as responsive as ever, now untethered. Whether you’re moving between desks or just want a cleaner setup, the wireless upgrade adds a subtle but satisfying layer of convenience.
