[!NOTE] This project is still under development. While almost everything works on Linux, Windows is a mess.
What is This?
MacroPad is a USB input device with six keys, three rotary encoders, a slider, and three OLED displays. All controls can be configured to send user-defined mouse or keyboard input to the computer. Multiple profiles are supported, allowing you to change between different key-assignments with the press of a button. Typical applications include audio and video editing, computer graphics, and presentations.
MacroPad implements standard USB HID (human interface) device classes and thus requires no driver. The only is software that is needed is a Program for Configuring it and potentially some software for the slider.
MacroPad is powered by a Raspberry Pi Pico using the RP2040 microcontroller.
How Does It Work?
When plugged into a computer, MacroPad presents itself as a three-in-one input device composed of a keyboard, a mouse, and a miscellaneous input device. All keys and rotary encoders can be configured to send keyboard or mouse input to the computer.
The slider is also an HID-class device that needs no driver. However, most operating systems don't know what to do with slider input and so they just ignore it. For that reason, you will most likely want to have a piece of software running that consumes these inputs and performs certain actions, like adjusting volume or changing the brush size in a drawing application. You can find several examples in the SliderApps folder.
Can I Have One?
MacroPad is not sold anywhere. In this repository, you can find all the necessary information and code to build a MacroPad yourself. Please have a look at the Building Instructions and the User's Guide. Building a MacroPad is not particularly difficult. As long as you can hold a soldering iron without touching the wrong end, you should be fine.

Questions
How big is the MacroPad PCB?
It measures 160 × 99.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MacroPad use?
29 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the MacroPad KiCad files?
From the 7vgn/MacroPad repository on GitHub, at the commit this page was made from: the board is PCB/MacroPad.kicad_pcb and its schematic PCB/MacroPad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MacroPad design in my own project?
Its repository states no licence, so its author keeps all rights: ask 7vgn before reusing the design.
