Getting started with ST25DV-DISCOVERY

Introduction

The ST25DV-DISCOVERY is a demonstration kit that evaluates features and capabilities of the ST25DV04K Dynamic NFC / RFID Tag.

The kit is composed of two boards:

• MB1283 (ST25DX_Discovery_Mboard): a microprocessor mother board, which includes a complement of hardware and software tools allowing the use the full STM32 Nucleo ecosystem. The board is powered through one USB connector.

• MB1285 (ST25DV_Discovery_ANT_C5): a daughter board, which embeds the ST25DV04K Dynamic NFC / RFID tag device. This daughter board provides a buffering data transfer capability and has a Class 5 antenna.

The communication link between boards is the I2C serial and the power is provided by the processor card or via energy harvesting. Specific data lines complete the pin connector assignment shared between cards.

A variety of demonstrations can be performed with this kit. The kit allows the users to develop and to test their own applications.

The MB1283 and the MB1285 boards schematics, BOM, gerber files, drivers and firmware are available at the STMicroelectronics website at www.st.com.
