WHAT IT DOES
What does it do?
This PCB business card draws power through NFC when tapped with a smartphone, causing 21 LEDs to start animating. It covers NFC energy harvesting, antenna fabrication, and assembly. Its creator says the project began as a way to learn KiCad.
KEY FEATURES
Key features
- Power an MCU and animations on 21 LEDs with smartphone NFC energy
- Use NFC energy harvesting without a battery
- KiCad-based schematic and PCB design
- Overview of antenna fabrication and assembly
EDITOR'S NOTE
Why did it stand out?
To keep the thickness and cost of an ordinary business card, the creator omitted the battery and powered the MCU and 21 LEDs solely through a smartphone's NFC field. The build record is interesting because it turns a KiCad learning project into a physical object that can be handed to someone.
