DC power supply boards are most used in all embedded system projects. Always power supply should be regulated & should source enough current to drive the different modules connected to the system. The +12V DC power supply board of I-labz makes you’re the power supply design circuit easier. The board has one input & one output terminal. The input terminal can be connected to any unregulated source of AC or DC supply. The input voltage rating of DC can be +12V to +20V. Generally an AC input can be fed to the input terminal, preferably a step down transformate of 12012 or 909 can be used. The input terminal is followed with the bridge rectifier circuit. So don’t worry about the polarity of input. The output stage is taken by the 7812 voltage regulator. A +12V DC power output can be used to connect any microcontroller development boards, motor drives, breakout boards etc. A LED is kept to a power indication on the board. This board will provide maximum up to 2A of source in current.
