Fixed Dual-Voltage 5V + 3.3V Power Supply Board dfr0031-g It is best to testAll electronics projects require power supply. This is a dual voltage power supply board that provides fixed 3. 3V and 5. 0V outputs from an unregulated DC input ranging from 7 12V. With its small size (1. 8" X 1. 4"), it can be easily enclosed inside a project box along with your project circuit. It uses LM78M05 and LD1117 3. 3V fixed voltage regulator chips that are both capable to deliver 500mA of output current. The unregulated DC input is
