Hi,I have designed a 65x85cm 2-turn PCB antenna but I cannot place it close to the damping resistors (I use the ST25R3916 for this). How would the horizontal tracks from the damping resistors to the antenna feed affect its performance, efficiency, fi...
hello want to sense some analog signal with passive modedoes ST25 able to work with passive mode?since i know that many researchers prefer ST product because of fidelity,really want that want to run project with ST products.can you help me with findi...

HiI would like to know if the ST25DV64K tag is going operate with a regular SO14443-A reader? I have already tested the tag against a Samsung S10 phone running the ST's app and is working perfectly. Best RegardsGilberto
We have a ST25 project running and able to read tags from 8cm distance. However, we would like to reduce this distance. Our idea is to reconfigure only "Receiver configuration register 3". Is this the best way ? Should I change "Receiver configuratio...
Dear SirsI have run PollingTagDetect application project on NUCLEO-L053R8 + X-NUCLEO-NFC05A1 board successfully. And I have transferred PollingTagDetect project code to NUCLEO-G070RB + X-NUCLEO-NFC05A1 platform. The terminal software can display IS...
Hi,I've noticed that C204 and C205 (tied to the ST25R3916 VDD_RF pin) are populated on the PCB Bottom Layer of ST25R3916-DISCO (The same applies to the NUCLEO board). These are the only components (necessary for the proper functioning of the board) t...
Hi,By checking the ST25R3916-DICSO BOM I've found the reference Y200 (27.12MHz Crysta Osc.l) The problem is I'm not able to find the part number NX2016SA STD-CZS-5 27.12MHz from NDK anywhere. What part is populated in the board? NDK does not give me ...
