mouse-joystick-pcb¶
Single-axis mouse joystick: RP2040 with GPIO isolation, one TMC5130A, torque bridge, brake current sink, analog angle output, InstrumentPort-Digital-50 taps, 36 V protected input with 12 V and 5 V regulators; v1.0 as built.
The assembled board with its design blocks numbered. On the site the picture is a model that turns, or the top render where WebGL is absent, and each number is a link to the block's page: its schematic, parts, ports and placement guidance. Read on the forge, the picture is the plain top render and the table below is the key.
The numbers are links; in a browser with WebGL this picture is a model that turns.

The numbers run left to right, top to bottom over the top view. The model is
3d/mouse-joystick-pcb.glb (metres, Y up, the board's x and y along X and Z); the drawing
3d/top.svg is 3d/top.png at
12.38 px/mm with one rectangle per block, the union of its footprints' courtyards; both and the
footprints of each block are recorded in 3d/hotspots.json.
Each block's page shows the render clipped around its rectangle.
Where to go¶
- Generated documentation: the renders, every document, the bill of materials and the enclosure reference.
- Design blocks: one page per placed block, with its schematic, parts, ports and place on the board.
- Subsystems from their recipes, and the MCU pin allocation.
- The navigation lists the board's own pages.
