This is a simple macropad built with Raspberry Pi Pico. See detailed description in my blog post at:

New! Wrote a short entry also for the Dial Controller:

Macropad support different models which you can change by pressing the top left key. Other buttons can be customized to do different things. This initial code includes the following modes:

The active mode is displayed in a small SSD1306 display.

Dial has simpler code. It'll use the KY-040 rotary encoder's switch function to switch between different modes. The current code includes four modes:

• Volume up/down
• Scroll up/down (as mouse wheel)
• Arrow keys up/down
• Fidget mode (doesn't do anything. Stress toy 😀)

Case is constructed of three parts. All parts can be printed without support. Parts snap-fit together without need for glue. STL files can be found from the stl-files folder.

Dial uses the same base part but add different panels on top of that.

If you copy the boot.py to your Pico then it won't show up as a separate drive. If you still have access to REPL on the device with e.g. Thonny then you can delete all the files with storage module. Try this in REPL and it'll erase the filesystem:

>>> import storage
>>> storage.erase_filesystem()

Note! You lose all installed modules etc. so you have to start from scratch uploading all files to your Pico after this.
