Gravity: UART & I2C NFC Module adopts NXP PN532, a highly integrated NFC communication controller, which supports various types of NFC smart cards or tags like the commonly used MIFARE Classic series and NTAG series in the market. Apart from the large PCB antenna design of better communication area and distance, the upgraded version joins the Gravity family by adopting a standard Gravity PH2.0-4P interface with I2C & UART composite rather than 2.54mm headers, making the wiring more convenient. A switch is added for conveniently switching between these two interfaces. When using the UART, you can easily read and write various NFC cards by using the common USB-to-UART converter and PN532-compatible PC software. When using the I2C interface, it can be used for various 3V3/5V controller such as Arduino, micro: bit, FireBeetle ESP32 and FireBeetle ESP8266.
