higher-voltage battery or power brick such as powering a 5-Volt Arduino from a 12-Volt car battery, or running 3.3-Volt sensors from a 9-Volt supply standard linear regulators often waste massive amounts of energy as pure heat.\u003csup class=\"superscript\" data-turn-source-index=\"1\"\u003e\u003c!----\u003e\u003c\/sup\u003e\u003c\/span\u003e The LM2596 step-down (buck) converter module is the ultimate solution. \u003cspan class=\"citation-222 citation-end-222\"\u003eBy utilizing 150 kHz high-frequency switching technology, it efficiently drops higher input voltages down to a stable,
