7 Key Features of the Ploopy Bean: A Unique Pointing Stick Mouse
When it comes to input devices, most of us stick to the traditional mouse or trackpad. But for those seeking something truly different, the Ploopy Bean offers a refreshing alternative. Built by a quirky Canadian company, this pointing stick mouse combines a familiar TrackPoint-like nub with four buttons and fully open-source QMK firmware. Whether you're a keyboard enthusiast, a tinkerer, or just tired of wrist strain, the Ploopy Bean deserves your attention. Here are seven things you need to know about this unconventional peripheral.
1. What Is the Ploopy Bean?
The Ploopy Bean is a compact pointing-stick mouse that eschews traditional sensors for a joystick-like nub. Instead of moving the entire device, you press the nub with a finger to control the cursor. It comes with four physical buttons—left, right, middle-click, and a fourth programmable button—all powered by QMK firmware, a staple in custom keyboards. This open-source firmware allows deep customization of every action, from button mappings to acceleration curves. The Canadian maker, known for silly names and innovative designs, aims to fill the gap in quality trackpoint peripherals.
2. How Does the Pointing Stick Work?
Similar to the TrackPoint found on old ThinkPads, the Ploopy Bean uses a pressure-sensitive stick that responds to force, not movement. You push the nub left, right, up, or down to move the cursor accordingly. The harder you press, the faster it goes. This method keeps your hands stationary, reducing arm fatigue and desk space requirements. The stick is precise enough for everyday browsing but may take a few days to master. Unlike optical mice, it works on any surface—even your lap. For users who prefer minimal wrist motion, this is a game-changer.
3. Four Buttons: More Than Meets the Eye
The Ploopy Bean includes four physical buttons: left click, right click, middle click, and a fourth button by default mapped to something useful like back or page up. However, thanks to QMK firmware, you can assign any key or macro to each button. Want the fourth button to open a terminal command? No problem. Need to switch DPI on the fly? You can program that too. The buttons themselves are tactile mechanical switches, providing satisfying feedback. This is a boon for productivity, as you can turn a simple mouse into a powerful input tool.
4. Open-Source Firmware: QMK at Its Best
One of the biggest selling points of the Ploopy Bean is its use of QMK firmware—the same open-source software that powers custom mechanical keyboards. This means you can customize every aspect of the device: button maps, pointer sensitivity, acceleration curves, layers, and even RGB lighting (if included). The firmware is stored on the mouse itself, so your settings travel with you. You can edit the keymap.c file and flash it via USB. For those who love tinkering, this is a dream come true. It also ensures long-term support, as the community can add features over time.
5. Compatibility and Connectivity
The Ploopy Bean connects via a detachable USB-C cable, making it compatible with Windows, macOS, Linux, and even some phones or tablets that support USB HID. There's no wireless option currently, which some may see as a limitation. However, the wired nature ensures zero latency and reliable connectivity. For keyboard enthusiasts, the Ploopy Bean fits right into a desk setup that already uses QMK, like a custom split keyboard. It also works with the Pimoroni Trackball module, if you want to experiment further.
6. Build Quality and Design
Made from 3D-printed plastic (often in bright colors), the Ploopy Bean feels sturdy but lightweight. The textured surface gives a good grip, and the base has rubber feet to prevent sliding. The nub is replaceable, so you can swap it for a different shape if desired. Inside, it uses a standard Pro Micro microcontroller, meaning repairs or upgrades are straightforward. The design is deliberately minimal—no ergonomic curves, no contoured grip—which keeps the price low and the production accessible. It's not flashy but functional.
7. Who Should Buy It and Where to Get One
The Ploopy Bean is ideal for Linux users, keyboard hobbyists, RSI sufferers, and anyone who wants to reduce mouse usage. If you already own a QMK keyboard, the Ploopy Bean integrates seamlessly into your workflow. It's available directly from the Ploopy website or through resellers like Pimoroni. Prices hover around $50-70 USD, making it affordable compared to other trackpoint peripherals. Keep in mind it's a niche product—don't expect mainstream ergonomics. But if you love open-source hardware and want a unique pointing device, the Ploopy Bean is worth every penny.
In conclusion, the Ploopy Bean stands out in a market dominated by generic mice. Its pointing-stick design, four programmable buttons, and open-source QMK firmware give you unprecedented control. While it has a learning curve and is wired-only, the benefits of reduced desk clutter and customizable input are hard to beat. If you're ready to think differently about how you interact with your computer, give the Ploopy Bean a try.
