The STEVAL-25R3916B 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 schematics. These documents are downloadable from www.st.com.
The STEVAL-25R3916B consists of two boards: STEVAL-M25R16B and STEVAL-D25R16B.
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.
