2X R558S Capacitive Fingerprint Acquisition Module Access Control Security Equipment Fingerprint Recognition Module

Descriere 2X R558S Capacitive Fingerprint Acquisition Module Access Control Security Equipment Fingerprint Recognition Module

Note: + 3.3V is used in R558S power supply design.
Power input is not allowed until the R558S is connected.
If the cable is plugged or unplugged (with hot plug), the electronic components of the R558S will be damaged. make sure that the power is cut off during cable plugging.
Poor power connection, too short interval power off and operation, or too large voltage drop pulse may cause the R558S not to be in a stable and normal working state, so it is necessary to keep the power input stable.
After turning off the power input, it is necessary to turn the power input again at an interval of more than 2 seconds.
