STEVAL-25R300KA Discovery kit for the ST25R300 high performance NFC universal device and EMVCo reader

The STEVAL-25R300KA kit allows the user to evaluate the features and capabilities of the ST25R devices, which are 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: STEVAL-M25B1 and STEVAL-D25R300A.

The STEVAL-M25B1 is a microprocessor motherboard, which embeds a 32-bit Arm Cortex™-M4 CPU with an FPU high-performance 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, features for ST NFC tag boards not used with the ST25R HF reader series.

The STEVAL-D25R300A is a daughter board, which embeds the ST25R300 highly integrated HF reader/NFC initiator/NFC target IC with an antenna etched on the PCB and the related tuning circuit.
