KiCad Advanced: Design a smart USB thumb drive

Source: https://www.udemy.com/course/kicad-advanced-design-a-smart-usb-thumb-drive/

What you’ll learn

• Route a 153-ball TFBGA eMMC chip using via-in-pad and dogbone escape techniques on a 0.5 mm ball pitch.
• Control differential impedance for USB signal pairs and verify trace geometry using an impedance calculator.
• Match eMMC data bus trace lengths to within ±3 mm using KiCad’s interactive length tuning tool and Net Inspector.
• Design a dual ideal diode OR-ing power path using the LM66100 for seamless, efficient dual-port power management.
• Create scoped KiCad DRC exceptions to document intentional design decisions without hiding genuine errors.
• Produce a complete, DRC-clean 4-layer PCB layout within the physical constraints of a USB thumb drive form factor.

Requirements

• Basic KiCad experience is required. You should be comfortable with schematic entry, footprint assignment, and simple PCB routing.
• No prior experience with BGA components, high-speed interfaces, or multi-layer boards is needed; this course covers all of it.
• A computer capable of running KiCad (Windows, macOS, or Linux). No hardware purchases required.
• The free NextPCB DFM Tool is used for impedance calculations. A Windows machine or VM is helpful but not essential.
