NFC module based on the NXP PN532 chip with built-in antenna on the board. The module has a Gravity connector for connecting the device to the most popular development kits such as Arduino or micro:bit. Memory communication can be done through one of the serial interfaces: UART or I2C. Thanks to the dual interface, the module can work with both microcontrollers and PCs via a USB-UART converter.
Near Field Communication (NFC), also known as short-range wireless communication, is a short-range wireless communication technology that allows contactless point-to-point data transmission (at a distance of ten centimeters) to exchange data between electronic devices.
