STEVAL-25R3916B

STEVAL-25R3916B is a kit that allows the user to evaluate the features and capabilities of the ST25R devices, which are a series of high-performance HF readers. The STEVAL-25R3916B consists of two boards: STEVAL-M25R16B and STEVALD25R16B. The STEVAL-M25R16B 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 bus. 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, an user-dedicated micro USB connector, features for ST NFC TAG boards not used with the ST25R HF reader series. The STEVAL-D25R3916B is a daughter board, which embeds the ST25R3916 highly integrated HF reader/NFC initiator/NFC target IC with an antenna etched on the PCB and the related VHBR tuning circuit.
