This page is just to show a quick and easy way to house the buck regulator PCB that I featured in my '5 Volt Solar Charger' project where I go into more detail about this very useful little board. Click here to go to that page. In this version, a single UK surface pattress box with blanking plate is used which has cutouts filed on each side for the connectors to enter and exit, creating a neat and inexpensive enclosure for these boards. I use this with my 12 Volt Distribution Box to supply 5 volts to charge my phone and other USB powered gadgets from the sun.

12 volts input is supplied via a short 2.1mm DC power lead and the output for the 5 volts is from a USB type C charging cable. Some charging cables have longer plugs on them which may need a bit of 'creative' filing, but I got lucky with this one from Anker.
