- Hardware-level Matrix Digital Rain screensaver with idle timeout
- 10x10 WS2812B LED Matrix divided into 4 high-speed hardware quadrants
- Custom Python (PyQt5) desktop studio for live two-way UART communication
- Real-time telemetry broadcasting and remote device configuration
- Open-source hardware and firmware
Hardware Specifications
- MCU: ESP32-S3-Mini
- Display: 100x WS2812B LEDs
- Level Shifter: 74AHCT125 (3.3V to 5V logic conversion)
- Inputs: 4-way D-Pad, 5 Action Buttons (A, B, X, Y, Start)
Bill of Materials (BoM)

Steps To Reproduce
Hardware
- The hardware design files are located in the
hardware/directory. Send the Gerber files to a manufacturer to produce the PCB. - Solder the ESP32-S3-Mini, 74AHCT125, WS2812B LEDs, and tactile buttons.
Firmware
- Open the
firmware/folder in VS Code using the PlatformIO extension. - Connect the ESP32-S3 via USB-C and upload the code.
Software
- Navigate to the
software/folder. - Run the pre-compiled executable:
software\MateRix_Cyberdeck_Studio.exe. - (Optional) To run from source, install dependencies with
pip install pyqt5 pyserial pyautoguiand runpython main.py.
Usage of AI
The usage of AI in this project was done with Google Antigravity, which acted as a pair programmer to help debug the C++ firmware, build the Python UI architecture, and verify the hardware pinouts and PCB routing strategies.

Questions
How big is the MateRix PCB?
It measures 40 × 69 mm and has 4 copper layers, 1.6 mm thick.
What parts does the MateRix use?
145 parts, built around the ESP32-S3-MINI-1-N8, CH224K, MP9943GQ(TOKMAS) and MIC5219-3.3YM5. 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 MateRix KiCad files?
From the FBIopeningUPP/MateRix repository on GitHub, at the commit this page was made from: the board is hardware/pcb/pcb.kicad_pcb and its schematic hardware/pcb/mcu.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MateRix design in my own project?
Its repository states no licence, so its author keeps all rights: ask FBIopeningUPP before reusing the design.
