    Product Description:

    AMS1117-3.3V power module for DC step-down voltage regulation. This fixed 3.3V output board is designed to supply regulated low-voltage power for electronic circuits, microcontroller projects, sensor modules, DIY experiments, and development boards.

    Core Selling Points:

    Built with an AMS1117 regulator chip for linear voltage regulation. The compact double-sided PCB includes a red power indicator LED and 2-pin single-row header connections for input and output. Its small board design supports installation in space-limited electronic projects.

    Technical Specifications:

    Model: AMS1117-3.3V. Module type: DC-DC step-down linear voltage regulator module. Fixed output voltage: 3.3V. Input voltage: output voltage + 1.45V to 12V DC. Maximum output current: 800mA. Connector type: 2-pin single-row header pins for input and output. PCB dimensions: approx. 2.5 cm × 1.1 cm. Weight: approx. 1.6 g. PCB design: double-sided board. Indicator: red LED.

    Package Contents:

    10 AMS1117-3.3V Power Modules.

    Before Purchase:

    Verify that the input voltage is within the specified range of output voltage + 1.45V to 12V DC. Pin definitions: VIN+ is input positive, VOUT+ is output positive, and GND is the common ground for input and output. Proper heat dissipation is recommended with higher input voltage or heavier loads.
