Positive power supply board. Its basically takes an input of 4.5-15V DC and outputs a constant voltage of 3.3V. It can supply a maximum of 0.8A of current at 3.3V.

The board comes with appropriate rectification, filtering circuit, a power indication LED. The module is very useful for the products which demand 3.3V at 800mA of current. It equips 3 pins where you can plug-in input and output, This offers ease of connection.

The Power Supply Mini Board is the ideal solutions, providing a positive supply at constant out for projects & systems etc.


  • Suitable for 4.5-15V AC/DC input with PCB Terminals
  • Power LED for Outputs
  • +3.3V Output Termination Points
  • Suitable for use with most +3.3V Microcontrollers
  • Dimensions: 13mm x 9 mm

Package Includes:

  • 3.3V AMS1117 800ma power supply module


  • Please do not work above the operating voltage, or it will be damaged easily.
  • The input voltage must be 1.5V or 2V higher than the output voltage, otherwise, it can not output enough power.
  • Please do not reverse polarity, or it will be damaged because of a short circuit.
