The Keybow OS is very lightweight and only requires a card with over 1 GB capacity, however, a class 10 rating is recommended for speed and reliability. The Raspberry Pi Zero will require a microSD card to hold the Keybow OS. We will also need a Raspberry Pi Zero WH or another Raspberry Pi Zero model with a soldered 40-pin header so that we can attach the Keybow MINI. We can also individually program the lighting for each key to react to our actions. These LEDs can be animated to show a custom user-defined pattern or sequence simply by uploading an image file to the device. This design allows them to shine up through the switch and into the keycap without adding extra space to the board. The Keybow MINI also includes three APA102 RGB LEDs that sit in the cavity underneath each key. ![]() The Keybow MINI comes with clicky Kailh Speed Gold mechanical switches, however, as the PCB uses Kailh hot-swap switch sockets, we can easily swap these for any Cherry MX-compatible switch. The kit includes the Keybow MINI board and plate, three mechanical switches, clear keycaps, acrylic baseplate, mounting hardware, and a 50cm Micro USB cable. The Pimoroni Keybow MINI comes as a kit that we need to assemble. ^Starter kit from Altronics (Without header) Use P5410 40-way header if buying this Starter kit. This guided us towards the Keybow MINI (3-key) kit from Pimoroni which offered the customisation we desired with hot-swappable key switches, an extensive scripting language, along with the simplicity of a ready-made PCB. We also didn’t want to go for a complete product like those offered by Elgato as they required proprietary software which restricted customisation and compatibility. This option would have provided us with the most customisation as we would fully control the design, however, it would also require strong soldering skills and result in a larger footprint. We considered creating the device from scratch using individual switches and breakout boards soldered directly to a programmable controller device. We decided the best solution would be a macro pad which could easily be programmed to execute these simple repetitive keystrokes. The commands can often be hard to remember so having them available as dedicated buttons would increase productivity significantly. These shortcuts are often found in advanced programs for streamers, programmers, designers, artists, and other enthusiast applications. For example, when programming devices and writing articles, we take advantage of various shortcuts and simple commands which could easily be mapped to an external input device for easy use. We often find ourselves performing repetitive tasks when using our computer which could easily be automated. ![]() BUILD TIME: under 1 hourĭIFFICULTY RATING: Intermediate CREDIT: Make repetitive tasks and computer shortcuts even quicker with the use of a Macro Pad.
