STMicroelectronics STEVAL-25R300KA NFC Reader Discovery Kit

STMicroelectronics STEVAL-25R300KA NFC Reader Discovery Kit allows the user to evaluate the features and capabilities of the ST25R devices, a series of high-performance HF readers. The kit comes with application notes, software applications, drivers, bill of materials (BOM), board schematics, Gerber files, and firmware binaries.

The STEVAL-25R300KA consists of two boards: the STEVAL-M25B1 and STEVALD25R300A. The STEVAL-M25B1 is a microprocessor motherboard that embeds a 32-bit Arm® Cortex®-M4 CPU with a high-performance FPU microcontroller.

This board is powered through the USB. It is based on an STM32L476 microcontroller and includes: an ST-LINK embedded debug tool interface, a 2.4” TFT LCD, LEDs, push buttons (reset and user), a mini USB debug connector, a user-dedicated USB Type-C® connector for USB 2.0, and features for ST NFC tag boards not used with the ST25R HF reader series.

Features

  • NFC Forum NFC-A, NFC-B, NFC-F, and NFC-V poller
  • NFC Forum NFC-A, NFC-F listener
  • Support for all five NFC Forum tag types in reader mode
  • NFC Forum type 3 Tag (NFC-F) host card emulation
  • NFC Forum type 4A Tag (NFC-A) host card emulation
