Developed and launched an NFC-enabled contact card as part of the hackclub/OnBoard repository, delivering a tangible prototype that allows users to store contact information and link to a website. The work included designing the PCB using schematic and Gerber files, integrating basic hardware concepts, and producing a comprehensive README in Markdown to document the project’s purpose, cost, and development process. By providing detailed documentation and production-ready design assets, the contribution improved onboarding for future collaborators and established a reusable foundation for subsequent NFC card enhancements. The project demonstrated skills in hardware design, PCB layout, and technical documentation using Markdown and PDF.
