DC-DC Converter Box for XL4015 Buck converter

This is a small box I made to house my XL4015 DC-DC Buck Converter. This enables me to plug-in any DC power supply up to 32V and then step down the output to any voltage from 0.8V to 30V DC. This unit can have its maximum output current set up to a maximum of 5 Amps (I recommended 4A for 80% load of the unit). The one in my picture has a 5V USB plug connection for the output, so I can charge any USB device.
