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.

Hi Markus´╝î
there are 6 pins on the module, v stands for voltage, g stands for gnd, tx stands for uart send, rx, stands for uart receive, w0 stands for wiegand 0 and w1 stands for wiegand. We do not see the S. please take a picture for the "S". we can see what we can help. thanks.
