Ask questions and find answers on ST25 NFC/RFID tags and readers, including connectivity implementations and antenna design.
I am wondering why it was necessary to use 6 layers PCB board for ST25RU3993 Evaluation board ? As outlined in the documentation, layers are as follow: Top Layer - RF GND Layer - Power Layer- GND Layer Routing Layer -Bottom GND Layer.I want to chang...
Where do I find top IC marking?? Should not it be in the datasheet? Customer wants to check parts coming onto their CEMRgds Yves
The X-Nucleo-NFC06A1 mentions 1.7W output power with differential antenna.I understand that the ST25R3916 chip is capable of 1.7W max output. I've been unsuccessful in finding out what the output power of the DISCO board is.
I’m using NFC05A1 and the STMF4xx-Nucle-Polling project. I’d like to interact with a Mifare classic card 1K. I am aware Stm won’t provide any code that would deal with encryption and this is not what I’m asking for. The issue I encounter is about t...

I would prefer range over data rate and was wondering if the NFC forum matching from the ST25R3911-DISCO board would apply to the 3916?
The X-NUcleo-NFC06A1 measure ~1.3uH, whereas the ST25R3916-DISCO measures close to 1uH.
Hi,I want to use the buzzer on the board as an indicator when the tag gets in the range of the reader and when it gets out. But I can't find anything about it in datasheet, except in the block diagram. To what pin is it connected on the MCU? How can ...
Hi,After I uploaded my custom firmware on board (the one that comes in SDK, a little changed ), I can't connect to the board. I tried to upload the official firmware back, but after it says Update firmware successfully, it tries to connect but just g...
