NFC card

Made according to the open source tutorial on instructables.

The original author Loann Boudin’s website https://www.instructables.com/PCB-Business-Card-With-NFC/

The NFC chip is NT3H1101W0FHKH. If you buy it individually, Taobao costs 6 yuan each with free shipping (the price has increased recently)

Resistors and capacitors are all packaged in 0402

The LED is packaged in 0603

You can use the APP: NFC Tools (you can search the Chinese version on Baidu NFC Tools) to read and write NFC cards. You can write text, URLs, and other content (download the APP and you will know what data can be written).

You can import pictures into the PCB file to beautify the card.

Finally, when placing a PCB order, choosing a thickness of 0.8mm is the best, but Jialichuang’s 0.8mm board cannot be patched. You can use a hot air gun to solder the chip yourself.

Special reminder: For students who only have a soldering iron and no tools such as a hot air gun/heating plate/reflow oven, try to choose Jiali bandage patches. The thickness of 0.2mm does not matter (except for Welding Emperor), because I bought three NFC chips. Use the electric soldering iron to solder only this one successfully in the end.
