R558S Capacitive Fingerprint Acquisition Module Access Control Security Equipment Fingerprint Recogn

Note: DC + 3.3V is used in R558S power supply design.<br> Power input is not allowed until the R558S is connected.<br> If the cable is plugged or unplugged (with hot plug), the electronic components of the R558S be . make sure that the power is cut off during cable plugging.<br> Poor power connection, too short interval power off and on 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.<br> After turning off the power input, it is necessary to turn on the power input again at an interval of more than 2 seconds.<br> Parameter:<br> Image pixels: 112*88<br> Resolution (dpi): 508<br> Sensor wear resistance: 200,000 times<br> Storage capacity: 100 fingerprints<br> Matching method: 1:1, 1:N<br> Whether there is self-learning: Yes<br> Whether there are lights: colorful lights<br> Fingerprint image collection time: Less than 180ms<br> Algorithm search time: Less than 100ms(50)<br> Overall recognition time: Less than 0.6s (50 pieces)<br> Startup time: Less than 50ms<br> False recognition rate (FAR): Less than 0.001%<br> True rejection rate (FRR): Less than 1%<br> Communication interface: UART (3.3V)<br> Communication baud rate (UART): 57600 (default)<br> Supply voltage: 3.3±0.3(V)<br> Maximum current: Less than 40(mA)/<br> Shutdown current: Less than 12()/ VADD<br> Operating temperature: -30°C to 70°C<br> Storage temperature: -40°C to 85°C<br> Relative humidity: 20% to 85% (non-condensing)<br> Antistatic capability (ESD): contact discharge ±8KV, non-contact discharge ±15KV<br> Working vibration: 10-150HZ, 0.5G, 3 axial directions, 1min/oct, 1 time/axial direction<br> Drop: can withstand a 1.2-meter drop to the concrete floor<br> IP rating: Front waterproof IP54<br> Colour:Photo Color<br> Material:pla<br> Package Contents:<br> 1 x Fingerprint Module<br> 1 x cable<br> Only the above packa
