AMS1117 3.3V power supply module is based on the AMS1117 3.3V voltage 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 standard.

Note: Do not exceed absolute maximum input voltage (12.5V) or output current. Exceeding maximum specifications can result in permanent damage to this module or any connected devices.

• Input: DC 4.5V – 12V (input voltage must be more than output voltage (more than 1V))
• Output: 3.3V, 800mA (load current cannot exceed 800ma)
• Onboard AMS1117 chip.
• Onboard power indicator to indicate power is turned on: Red LED.
• Output voltage interface, connection to facilitate the experimental.
• Specially designed two pin mounting holes, can be directly fixed on the whole expansion board for experiments.
• Small Compact Size, 4Pin Type, Breadboard Friendly.
• 2P single row pin input and output for easy connection
• Dual-panel design, the layout is nice
