Описание
Gravity seriescommunication module with NFC tag manufactured by DFRobot. It uses the NXP PN532 integrated communication controller, which supports various types of smart proximity and bounce cards or NFC tags, including the MIFARE Classic and NTAG series commonly used on the market. It uses two buses: an I2C interface and a UART interface, which are selectable via a switch built into the board. It is compatible with 3.3V / 5V powered microcontrollers, which include Arduino, micro:bit, FireBeetle ESP32 or FireBeetle ESP8266.
The product iscompatible with ArduinoA product wiki page is available on the manufacturer's website, which includes a user guide and library for the Arduino IDE environment along with sample program code.
NFC tag is used in contactless payment systems.
