“In this instructable I show you how I made a simple RFID UID reader which reads the UID of a Mifare RFID card.
The program is quite simple and on a breadboard the reader was quickly made. Then I soldered it all on a piece of perf board and I designed an enclosure for it.
It has a built-in LiPo charger.
I bought the components from Aliexpress:
- Oled screen (SPI)
- MFRC522 RFID module
- TP4056 charger IC
- Arduino pro mini 3.3V 328P
- LiPo battery”
