I received a buck converter in the post today. The unit has a 17vdc range input and a regulated 5vdc output. The unit will allow me to place the Raspberry Pi outdoors and use a sealed lead-acid battery as power source for day and overnight operation. The battery will have a Xantrex PWM 50W charge controller charging the battery from a single solar panel dedicated to powering the RPi, alone.
The RPi has a micro-B USB connector that is used for power input connection. I will take a matching connector and attach the other end to the buck converter.
A buck converter is a voltage converter that drops and input voltage to a lower level. A boost converter is a voltage converter that raises an input voltage level to a higher level.
The RPi is mounted on a circuit board along with a couple of other devices.
