VariVolt: Variable voltage power supply with 3 preset voltages.

One of the biggest challenges when building projects is finding and using a reliable source to power your circuitry. Swizzle Circuits has designed a variable power supply around the LM317; one of the most trusted voltage regulators of all time. Once completed, the kit will allow you to choose between the most popular voltage levels used in modern circuits: 3.3VDC, 5VDC and 9VDC. Our kit features standard output jacks for jumper wires and a large rotary switch for the voltage selection. Easy to solder and use, out VariVolt will be in engineers’ toolboxes for years to come.
