1) Does ST make an NFC tag chip that has even one general-purpose, digital input detectable by the tag reader?2) Can a ST25DV04KC's energy harvesting really power up an 8-bit MPU long enough to take a sensor reading and write back via i2c? The MPU wo...
Hi All!I hope this is not too much of a dumb question, but does the M24SR64-Y NFC IC (on the b-l475e-iot01a evaluation board) support peer-to-peer NFC comms.?If it does, is there any library code to assist in this? The code in en.stm32cubel4_v1-18-0 ...
I have learned that the energy of the EH pin of ST25 is too small to meet the needs of the project. Can I use Qi wireless energy collection to solve the problem of energy collection and realize the transmission of sensor signals to the reader without...

Hello,I'm trying the X-NUCLEO-NFC08A1 in combination with the NUCLEO-L476RG. I have programmed the demo firmware NFC08A1_PollingTagDetectNDEF.It detects tags but reading distance is very poor. ( less then 1 cm for small ISO-15693 tags).Is there a GU...
I have been paying attention to the energy collection function of ST25, and I want to make ST25 collect energy to power low-power MCU through NFC. I want to know how this picture is realized, and do you have specific models and instructions?
我最近尝试实现NFC WLC功能，但是X-NUCLEO-NFC07A1中EH的能量输出仅为10mw，无法为NUCLEO-L476RG供电。直到我关注了NFC无线充电功能，却没有找到电池充电芯片的细节，我可以用STBC15实现NFC WLC功能吗？
I want to know the wireless power supply principle of NFC WLC, can I verify the effectiveness of wireless power supply through ST25DV series? Where the listener has a power receiver, how to achieve wireless charging?
I understand that I have exited the NFC WLC function and I currently have X-NUCLEO-NFC07A1. How do I charge the WLC-Listener using the battery charging function shown in the legend?

I need to use NFC to obtain several hundred watts of energy to drive the MCU of L4 to complete other tasks, Can I use ST25 and antenna to achieve this? Can the energy obtained from it be used to charge NFC? Can I use the QI standard provided by ST Co...
Can the NFC WLC shown in the picture be purchased? I need to do the passive test project. Can use NFC to collect energy to power MCU to complete other tests.
