3.3V Design Background: As electronics enthusiasts , you are not 'll find a 3.3V power supply and tangled, is not the will to power is not enough to expand the number of interfaces and distress ? Such experience , I believe that people will engage in electronic design often encountered . To facilitate that we can find a safe high performance , ease of use , power regulator rich expansion interface module , shop designed in such a transfer 3.3v 5v power regulator module, which applies to single-chip design project requires 3.3V power supply electronic equipment. Meanwhile , some of the electrons can be designed to facilitate the expansion of power . 1 Input : DC 4.5V--7V ( input voltage must be higher than the output voltage to 1V or more. )2 Output : 3.3V, 800mA ( load current must not exceed 800ma)3 pairs of panel design, layout nice ;4 specially designed two pin mounting holes , can be directly fixed on hole board for extended experiments ;5 input and output using 2P single row pin for easy connection ;6 PCB board size : 2.5cm * 1.1cm7 with power indicator light ( red ) 5V Design Background: As electronics enthusiasts , you are not 'll find a 5.0V power supply and tangled, is not the will to power is not enough to expand the number of interfaces and distress ? Such experience , I believe that people will engage in electronic design often encountered . To facilitate that we can find a safe high performance , ease of use , power regulator rich expansion interface module , shop designed in such a 5v power regulator module, which applies to single-chip design projects that require electronic equipment 5V supply . Meanwhile , some of the electrons can be designed to facilitate the expansion of power . 1 Input : DC 6V - 12V ( input voltage must be higher than the output voltage to 1V or more. )2 Output : 5.0V (+-0.05v error ), 800mA ( load current must not exceed 800ma)Three pairs of panel design, layout nice ;4 specially designed two pin mounting holes , can be directly fixed on hole board for extended experiments ;5 input and output using 2P single row pin for easy connection ;6 PCB board size : 2.5cm * 1.1cm7 with power indicator light ( red )
