PROFILE
Jackie
Jackie Lee contributed to the ISS-PCB repository by designing and updating hardware systems for embedded applications, focusing on schematic capture and PCB layout using KiCad. Over four months, Jackie delivered features such as integrating an ADC expander, enhancing I2C signal integrity with pull-up resistors, and adding power isolation for improved component interaction. She also implemented dual stepper driver support and optimized power distribution and grounding on the Motor-MK1 board, addressing reliability and manufacturability. All changes were hardware-focused, traceable through detailed commits, and prepared for validation, demonstrating a methodical approach to hardware engineering and robust schematic design.
