Pinout 125Khz RFID Module

Post by markus-schwarz » Thu Apr 05, 2018 5:47 pm

Hi,

can anyone tell me, what the Pin labeled with an "S" on this module is for? Mini 125Khz RFID Module - Pre-Soldered Antenna (35mm Reading Distance) It seems to be always pulled to "high"-level ...
If there's a special category in this forum for this kind of product/question, could an admin please move this topic to there? I couldn't find a suitable category.

Thanks,
Markus
