[Not iterated] PCB subway card

This file has been open sourced on github, but it is only an AD file. It took a while and Lichuang EDA reset it. By the way, a new creative version was included, inspired by the up owner of station b (UID: 294000273, 不忘初心MCU).

There are four versions in total:

1 decorative version

2 NFC version

I can't find the picture, but there is only a usage video. Buy a card with a little balance left, take out the chip inside and put it on the PCB, and you will get a PCB subway card! Actual testing can be recharged.

3 GPS version

The first time I used SMT, I found that the IC package of the driver was too small... I cried to death... This version is invalid. In the future, when the four-layer board is learned, a Bluetooth version will be released...

So many LEDs are in vain...

4 love DAC version

I made this version for my girlfriend! (     ) I’ll go make samples of 2333 in a few days, (Dog head saves life) I happened to have a piece of RC on hand, so I started drawing...

5 New version of Xiamen Metro

This time, the driver chip package was redrawn and RGB lights were used to simulate the site:

Using Jialichuang SMT (fast and good 2333)
