AMS 1117 3.3 V DC - DC Step down Converter
AMS 1117 3.3 V DC-DC Step-down Converter is a power supply module based on the AMS1117 3.3V regulator. It is capable of regulating a wide range of input voltage (4.0 to 12V) down to a fixed 3.3V output at up to 1A (Vin = 4.5V). Standard 0.1" header pins provide a means of connecting to its input and output terminals. These header pins have also been conveniently placed so that the module can be inserted face down into the standard.
