This is a power board kit that can be freely varied from 3V to 9V.
Can be used for various experiments or as an alternative battery power supply.
The voltage selection pin makes it easy to output 3V, 6V, 9V.
There is a thru (pass) terminal of the input, and the 12V used for power supply can be used as output.
It can be used simultaneously with the output that passes through the variable regulator, so you dont need more than one power supply when using a substrate that requires different power supplies.
Includes a poly switch (self-returning fuse) for over-current protection.
If output short circuit, overcurrent continuity etc. occurs, the output circuit will be shut.
In addition, when the poly switch is working and the output circuit is shut off, the LED (yellow) will light up so you can check the working condition at a glance.
This kit requires soldering
