so no soldering is required to use it with an appropriate 16-pin socket or solderless breadboard

higher frequencies might work but were not tested

Peak current can reach 40 mA

Pololu 5V Step-Up/Step-Down Voltage Regulator S9V11F5 Abverkaufen 6 A stall torque atThe Pololu step up step down voltage regulator S9V11F5 is a switching regulator (also called a switched mode power supply (SMPS) or DC to DC converter) that uses a buck boost topology. It takes an input voltage from 2 V to 16 V and increases or decreases the voltage to a fixed 5 V output with a typical efficiency of over 90%. Note that this regulator requires an input voltage of at least 3 V to start, but it can operate down to 2 V after startup.
