README
README.mdChromaDeck
ChromaDeck is a massive, open-source, fully custom USB MIDI Control Surface designed for streaming, video editing, and live audio mixing. Built around the powerful STM32F407 microcontroller, it features 4 motorized-style slide potentiometers (faders), 6 rotary encoders, 8 tactile push buttons, and a dazzling array of 30 WS2812B individually addressable RGB LEDs. It also features a high-speed 4.0" TFT LCD module driven via FSMC for lightning-fast UI updates.
What makes ChromaDeck unique is its Fort Knox Quad-Rail Power Architecture. It safely isolates the massive current spikes generated by 30 LEDs using dedicated Texas Instruments buck converters (TPS568215 and TPS562200), ensuring the analog fader readings and the digital MCU logic remain pristinely clean and jitter-free.
How to Use It
- Plug it in: Connect ChromaDeck to your PC using the USB-C port (provides data) and plug in the 12V DC barrel jack (provides the heavy-lifting power for the LEDs and display backlight).
- Launch the Companion App: The companion software detects the board over USB.
- Map your controls: You can map the 4 faders to OBS audio sources, system volume, or MIDI CC channels in your DAW. The 6 encoders are perfect for timeline scrubbing in Premiere Pro or adjusting EQ bands. The 8 tactile buttons can launch macros or switch scenes.
- Enjoy the Lightshow: The 30 LEDs provide real-time VU meter feedback for your faders and dynamic RGB backlighting for the encoders.

Source Files & Instructions
This repository contains everything needed to replicate the design from scratch.
- Hardware Design (KiCad 8): Located in the
/Hardware/board/folder. This includes the full schematic (.kicad_sch), the PCB layout (.kicad_pcb), and the project file (.kicad_pro). - 3D Models: Step files and STL files are located in the
/Hardware/3D/folder. - Firmware (PlatformIO / C++): Located in the
/firmware/directory. Powered by the STM32 HAL. - Companion App: Located in the
/companion/directory.
Build Instructions
- PCB Fabrication: Zip the contents of the
/Hardware/board/folder (or generate Gerbers) and upload them to your favorite PCB manufacturer (e.g., JLCPCB, PCBWay). - Assembly: Follow the
BOMto acquire all parts. The smallest components are 0603, which are hand-solderable with patience, but a stencil and hot plate are recommended. - Firmware Flashing: Connect an ST-Link V2 to the 4-pin SWD header. Open the
/firmware/folder in VS Code with the PlatformIO extension installed, and click "Upload". - First Boot: The debug LED on PC13 will blink, indicating the STM32 is alive.
Sanity Checks & Quality
This design has been rigorously sanity-checked for:
- Reverse polarity protection (P-Channel MOSFET on the 12V input).
- ESD protection (USBLC6-2SC6 on the USB lines).
- Proper decoupling (100nF caps at every IC power pin and every WS2812B LED).
- Solid mounting (4x M3 mounting holes for standard standoffs).
- Hardware debouncing (10nF caps on every encoder and switch).
