The regulated power supply accepts unregulated intputs from 12V to 15V AC or DC and gives regulated output of 3.3V  5V and 12V suitable for  projects which needs precise voltage to work. The input can come from step down transformer. Since board has diode  bridge input polarity does not matter.All outputs are brought to screw terminal. There is also an unregulated output voltage to drive high current loads like relays and motors.

Hand vein patterns are unique and universal. Vein pattern is used as biometric feature in recent years. But, it is not very much popular biometric system as compared to other systems like fingerprint, iris etc., because of the higher cost. For conventional algorithm, it is necessary to use high quality images, which demand high-priced collection devices. The two approaches for vein authentication are repeated line tracking and maximum curvature method. Currently we are working on maximum curvature method. Here we are putting forward the new approach for low cost hand dorsa vein pattern acquisition using low cost device and proposing an algorithm to extract features from these low quality images which are used for personal authentication. 

Order Code : RDL/PVA/13/001/V1.0 

These relays are suitable for domestic appliance, office machine, audio, equipment, automobile, etc. The relay plays the role as a protector or a circuit switch. It can protect your electric equipment’s very well. 

Order Code : RDL/RPM/13/001/V1.0

DB9 ports are very common on most types of microcontroller, where they can be used to communicate with a PC or other serial devices.

Order Code : RDL/DBM/13/001/V1.0

This is an IC base for 40 Pin IC's. This is used as a place holder for the 40 pin IC chips and is used in order to allow safe removal and insertion of IC chips because IC chips may become damaged from heat due to soldering.This base is very useful for your circuit because if your IC burns out you can easily change the IC without the need of desoldering.
