Regulators

Variable Voltage Regulator Board Kit Rev 2 - These Rev 2 Variable Voltage boards have been re-designed to be made a bit smaller and all the fixes from the rev 1 board have been applied. The voltage range is adjustable from 0 to 7 volts (can be changed with a higher resistance pot). An external 50k potentiometer can be used on these boards also, just wire to the appropriate pins. They work great and have minimal voltage drop due to the self correction of the regulator. Board dimensions are 33mm x 10mm and easily fit into an AA battery slot. You will need to provide your own enclosure (for example, 3xAA box). These are still easy to assemble and work great.

Each Variable Voltage Regulator Board Kit Includes :
Circuit board
2 10k ohm resistors
50k pot
