It is based on the NFC ST25DV04K device embedded on a daughter card using a Class 5 antenna and a STM32 processor driving a mother board. A dedicated software stored in the Flash memory is provided. The ST25DX Discovery Mboard is available in two versions. The demonstration edition includes all of the standard edition features with Wi-Fi , and BLE (Bluetooth Low Energy) modules to demonstrate various connectivity use cases. The standard edition is used to achieve the demonstration edition features. The ST25DV04K device is a dynamic NFC/RFID tag IC with a dual interface. It embeds a 2 4 Kbits EEPROM memory. It can be operated from an I C interface, or by a 13.56 MHz RFID reader, or by a NFC phone. The ST25DV04K Class 5 antenna daughter card, included in the kit, can be replaced by Class 1 or Class 6 antennas. For this purpose an ST25DV antennas bundle is available for ordering. Its references are available on the ST web site. 2 The ST25DV I C interface uses a two-wire serial interface, consisting of a bidirectional data 2 2 line and a clock line. The I C two-wire serial interface behaves as a slave in the I C protocol. The RF protocol is compatible with ISO/IEC 15693 and NFC Forum Type 5 tag contactless interface.The boards are powered through the USB connectors.
