Gravity PN532 NFC RFID Module with UART and I2C

The DFRobot Gravity NFC RFID module uses an NXP PN532 chip. The PN532 is a highly integrated NFC communication controller that supports various types of NFC smart cards or NFC tags as well as RFID cards like MIFARE Classic Series and NTAG. The module features a large PCB antenna that can read NFC chips up to a distance of 10mm. If you control the Gravity NFC RFID module via the I2C interface, you can easily use it with various microcontrollers such as Arduino, micro:bit, FireBeetle ESP32 and FireBeetle ESP8266 or Raspberry Pi. NFC (Near Field Communication) is a wireless technology that enables contactless point-to-point data communication between devices at a distance of about 10mm. It is commonly used in applications such as access control systems, contactless payment systems, meal cards, smartphone NFC applications, etc.

Features of Gravity NFC RFID Module:

• Easy connection via the I2C Gravity interface
• Onboard PN532 chip, supports various NFC/RFID cards like MIFARE/NTAG2xx, etc.
• Three selectable communication interfaces: I2C and UART, configured via switches.
• Connection cable with Dupont Female. So this module can be easily connected to an Arduino, ESP32, ESP8266 or Raspberry Pi.
• Program examples for Arduino available
