The compact (0.4"×0.5") D24V6F5 switching step-down (or buck) voltage regulator takes an input voltage between 7V and 42V and efficiently reduces it to 5V while allowing for a maximum output current of 600mA. The pins have a 0.1" spacing, making this board compatible with standard solderless breadboards and perfboards.

For our purposes (powering FPV/FC gear e.t.c in mini quads) the SHDN pin should be directly connected to VIN to permanently enable the board.

Important information from the manufacturer:
When connecting voltage to electronic circuits, the initial rush of current can cause voltage spikes that are much higher than the input voltage. If these spikes exceed the regulator's maximum voltage (42V), the regulator can be destroyed. In our tests with typical power leads (~30" test clips), input voltages above 20V caused spikes over 42V. If you are connecting more than 20 V or your power leads or supply has high inductance, we recommend soldering a 33µF or larger electrolytic capacitor close to the regulator between VIN and GND. The capacitor should be rated for at least 50V.
