README
README.mdled-strip-controller
The LED Strip Controller is a RP2040 (Pi Pico) based controller for a 12V DC LED strip we had lying around. Instead of spending £20 on a cheap controller, why not spend much more (and countless hours) on making our own absurdly overengineered one!?
Firmware
The firmware, located in firmware is WIP.
Hardware
PCB
The entire controller is based around one PCB available in the hardware/board directory. It is designed using KiCad.
Box
There is a box that can be 3D printed to fit the PCB and its components well. It is in the hardware/box directory, and
was designed using FreeCAD.

Questions
How big is the Led strip controller PCB?
It measures 65 × 65 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Led strip controller use?
21 parts, built around the L7805, TSOP2438 and IRL520NPBF. 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 Led strip controller KiCad files?
From the inventor02/led-strip-controller repository on GitHub, at the commit this page was made from: the board is hardware/board/led_strip_controller.kicad_pcb and its schematic hardware/board/led_strip_controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Led strip controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask inventor02 before reusing the design.
