Business Card V2

Jun 2025 - Jul 2025

Version 2

This is the second version, featuring the addition of a MicroSD card slot, reinforced ESD protection and some layout changes. To ensure a continuous GND plane below the USB2.0 signal lines, I designed the board as a 4-layer PCB.

The previous version was powered up and tested. However, some flaws prevented direct access via USB. These issues have been resolved, and the board is expected to trigger computer scripts once the components and firmware are added.

Version 1

This is the first version of my very first PCB design.
