DFR0231-H Gravity: UART & I2C NFC Module

DFRobot DFR0231-H Gravity: UART and I²C NFC Module integrates NXP PN532 NFC communication controller that supports MIFARE classic series, NTAG series, and various NFC smart cards. This module offers the upgraded version of the Gravity family that adopts the Gravity PH2.0-4P interface with I²C and UART composite, making the wiring more convenient. A convenient switch is added to switch between these two interfaces. This Gravity module can read and write various NFC cards using a USB-to-UART converter and PN532-compatible PC software through UART. This module is used in various 3.3V/5V controllers such as Arduino, micro:bit, FireBeetle ESP32, and FireBeetle ESP8266 when using the I²C interface.
