Hello @Shikamaru
The USB dongle is a product designed based on NXP's NFC and MCU. This is a third-party product and is not a product of NXP. This USB dongle implements all the features of the PN7150 reader, and its external interfaces include NFC and USB. Based on your design requirements, I understand that it should be integrated into your STM32 system through the USB interface. If this is the case, what you need to do is what is the communication protocol of the USB dongle to external communication through the USB interface, and then your STM32 end can also implement the same protocol, because the NFC behavior and performance is completed by the USB dongle. Unfortunately, USB dongle is not a terminal product of NXP, we are not such a protocol, so it is recommended that you consult MIKROE. Hope to make myself clear.
