Work History
Custom Arduino UNO Development Board Design
University of Colorado at Boulder
Boulder, CO
08.2024 - 12.2024
- Designed a high-performance 4-layer custom "Golden Arduino" board from scratch using Altium Designer, including schematic and PCB layout.
- Integrated a smart measurement system on the board’s backside to measure Thevenin voltage and resistance of voltage sources or VRMs.
- Optimized circuit design with ferrite bead filters, decoupling capacitors, via stitching, and ground planes to minimize interference and noise.
- Programmed the bootloader to manage ATmega328 startup and enabled high-density peripheral connections via blind vias.
- Tested with 10x probes and an oscilloscope; results showed significantly reduced crosstalk, signal reflection, and voltage noise compared to commercial Arduino Uno boards.
