8- R2 resistor is variable potentiometer 10k
9- C2 capacitor is 10uf
10- c3 is 104 no capacitor
11- switch for on/off 5A rated
12- Vero board
This all items you need to make the circuit.
This circuit can easily give you any voltage within 2 to 32 and up to 3A current.
Here you can use this DC regulated power supply board -
1 - Battery charging like
12v lead acid battery - set voltage 15v
6v lead acid battery - set voltage 9v
3.7v lithium ion battery charging - set voltage 4.2v
12v lithium battery charging - set voltage 12.6v
24v lithium ion battery charging - set voltage 25.6v
2- can power up any circuits for testing easily.
3- can run small and medium size motor very easily
4- works great with a 555 motor, 365 motor, 390 motor.
5- works great with LED also.
