Pololu 5V, 1A Step-Down Voltage Regulator D24V10F5 POL_Wireless and you can readily modifyThe compact (0. 5 0. 7) D24V10F5 synchronous buck voltage regulator takes an input voltage of up to 36 V and efficiently reduces it to 5 V while allowing for a maximum output current of 1 A. This regulator offers typical efficiencies between 85% and 90% and has a very low dropout, so it can be used with input voltages as low as a few hundred millivolts above 5 V. The pins have a 0. 1 spacing, making this board compatible with standard solderless
