K202+R503 Dc12V Low Power Consumption Control Board + R503 Module

Excellent. Delivery 35 days from the time of order. Interesting fingerprint controller. The seller perfectly packed everything, the board in its anti-static package and in the pupirks, the fingerprint sensor in its anti-static and pupirks. Attached instruction for programming. Admin prints are added, custom ones too. There is a multi-speed resistor to set the opening time. Relay with dry contacts, I.E. On the contacts of the relay there is no voltage, which means you can switch any voltage. The sensor reads wet fingers, but frankly raw No. Also when the raw sensor itself also does not read, everything is like on the phone when you use the fingerprint sensor. I'm happy with the purchase. While I played on the table, I'll put it on the wicket in the spring. Thank you.

Device is consistent with the description. Podłączyłem carefully according to the chart and was small konsternacja because time relay action originally was so set that in general it not wyłączał. The effect was such that tile very be nagrzała in short time. Thought that either got defective goods or same it spaliłem. Finally skręciłem time opening relay for minimum and began to work. As already the opanuje device which is by no means difficult It works very well. Tile when standby is cold. Goods packed was in carton box making well zabezpieczało delicate plate. Delivery time for PL equal 2 weeks. Recommend

Product looks good. Made some tests and works perfectly. But the manual is missing information about the reset manufactures. Detail, to reset the module, is necessary to register 1 biometrics, otherwise it allows access any biometrics (without restriction). Care to reset.

Works fine. At the first turn on it is better to completely reset, then enter prints. If the food is lost, the prints are not washed. Checked when turned off for a few hours. I never tried it again. In general, quite worthy.

Device of beginning to defect, seller not helpful, asks again the same. I want to own cost resend, CA 42 euro! Now the device would have claimed works and I had it destroyed. Warning before this shop!!!!

Works perfectly, the only "but", after remembering 15-20 prints refuses to remember more, although in the description promised 120. It flashes as if it remembers, but then these prints do not react.

Fast delivery, excellent packing. Everything came intact. The sensor is excellent, recognizes quickly, confidently. There is an adjustment of the time on the relay. I recommend to buy.

I order the second time, the first set everything works, the prints respond in 1-2 seconds, connected to the intercom ComMAX and the electromechanical lock works on Hurray.

In appearance, everything is as in the description, the sensor of the imprint is a metal case, I have not checked the work yet, as I will check the feedback.

The seller recommend the product came quickly all the Clas checked everything works put five stars.
