The ST25R3916-DISCO kit comes with application notes, software applications, drivers, BOM (bill of materials), board schematics, Gerber files and firmware schematics. These documents are downloadable from www.st.com. The kit is composed of two boards: 1. The MB1396 (ST25 Discovery Mboard) is a microprocessor motherboard which embeds a 32-bit Arm Cortex-M4 CPU with FPU high-performance microcontroller. Note: Arm is a registered trademark of Arm Limited (or its subsidiaries) in the US and/or elsewhere. The MB1396 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 with touch screen capability LEDs Push buttons (reset and user) A mini USB debug connector A user-dedicated micro USB connector Features for ST NFC TAG boards not used with ST25R HF reader series 2. The MB1414 (ST25R3916 Discovery DB) is a daughter board, which embeds the ST25R3916 a highly integrated HF reader / NFC initiator / NFC target IC and antenna etched on the PCB with its VHBR tuning circuit. The ST25R3916-DISCO kit (MB1396 and MB1414) schematics, BOM, Gerber files, drivers and firmware sources are downloadable from www.st.com. Figure 1.
