Video Tutorial

Step 1: Prepare materials and tools

The boards and main parts we need.

• PN532 *1
• USB2TTL *1
• Bluetooth Serial Board *1
  iOS only support Bluetooth 4.0+ version
  Android support Bluetooth 2.0+ version
• Dupont Line *4
• Battery *1

Step 2: Test PN532 on USB2TTL

Testing on PN532 on USB2TTL is necessary to make sure this 2 module work can work well and can forward to next steps. Or you can pause here if you just need PN532 to work on USB.

Connection of USB serial Module and PN532 Module:
        VCC ->> VCC
   USB  GND ->> GND  PN532
Serial  TXD ->> RXD  Module
        RXD ->> TXD

Software or apps we’re using for testing.

• MTools, RFID Tools, Serial Bluetooth Terminal on Android
• Coolterm on MacOS or Serial Port Utility on Windows

Step 3: Config Bluetooth Module

Bluetooth Serial Module I’m using is HC-06, which has a default Baud at 9600. So it has to be adjusted to 115200 which PN532 works on.

Connection of USB serial Module and Bluetooth Module:
         VCC ->> VCC
  HC-06  GND ->> GND  PN532
    SPP  TXD ->> RXD  Module
         RXD ->> TXD

Step 4: Connect PN532 and Bluetooth Module

Connect PN532, Bluetooth serial module and the battery to finish all work.

Connection of PN532 and Bluetooth Module:
         VCC ->> VCC
  HC-06  GND ->> GND  PN532
    SPP  TXD ->> RXD  Module
         RXD ->> TXD

Step 5: Bingo! Here it is!

Now try to enjoy read and write with this wireless reader. 😀
