The Mini HRM402 Voltage Booster measures just 64mm x 35mm so it's tiny enough to fit in other equipment and actually contains a built in LED voltmeter. The output voltage can be turned up to 30V DC by simply turning a small adjuster on the PCB and by pressing a switch on the PCB you can oscillate between the input and output voltage so it’s very engineer friendly!
