Frequently Asked Questions
What NFC protocols does the ST25R3911B kit support?
The ST25R3911B NFC Development Kit supports ISO14443A, ISO14443B, ISO15693, and NFC Forum Type 1 through Type 4 specifications. This comprehensive protocol coverage enables compatibility with virtually all commercial NFC tags, cards, and devices worldwide including MIFARE Classic, MIFARE DESFire, FeliCa, and smartphone NFC implementations.
Can I use this kit for both reader and card emulation applications?
Yes, the ST25R3911B supports both reader/writer mode and card emulation mode. In reader mode, it can scan and read NFC tags and cards. In card emulation mode, the kit itself acts as an NFC card that can be read by external NFC readers and smartphones. You can switch between modes in firmware or implement simultaneous multi-mode operation for advanced peer-to-peer applications.
What is the typical communication range of the ST25R3911B?
The communication range depends on the NFC protocol and antenna design. Standard communication range is 5-10 cm for ISO14443A/B protocols with the included antenna. Extended range up to 15-20 cm is achievable with optimized antenna design and increased field strength. The kit includes configurable field strength settings allowing you to balance range requirements with power consumption for your specific application.
Is the development kit compatible with STM32CubeIDE?
Yes, the ST25R3911B Development Kit is fully compatible with STM32CubeIDE and includes pre-configured projects for rapid development. The kit comes with STM32CubeMX device configuration files, HAL drivers, and middleware libraries optimized for the STM32L476 microcontroller. The integrated ST-Link debugger enables seamless debugging and flash programming directly from the IDE.
What power consumption should I expect in different operating modes?
Active NFC communication draws approximately 50-80 mA depending on field strength and protocol. Idle mode with NFC field detection enabled consumes around 10-15 mA. Low-power sleep mode with wake-on-NFC capability draws less than 5 microamps. The STM32L476 provides multiple low-power modes allowing optimization for battery-powered applications. Actual consumption depends on firmware implementation and peripheral usage.
