Hw-133-v1.0 Datasheet ((hot)) Jun 2026

The Hw-133-v1.0 includes a small blue potentiometer marked "103" (10kΩ). Turning it adjusts the trip point for the digital output.

The module is a "go-to" for makers because it handles variable input sources (like 7.4V or 12V batteries) and converts them into a stable 5V or 3.3V supply for microcontrollers. It is frequently found in: Aviation Models : Used where weight is a critical factor. Environmental Monitoring Nodes

Ensure the module is placed in an area with clear airflow or mount it inside a 3D-printed enclosure with ventilation slots .

: Use a small screwdriver to turn the silver potentiometer screw. Clockwise : Increases voltage. Counter-clockwise : Decreases voltage. Hw-133-v1.0 Datasheet

3A (Maximum), though 1.5V–2A is recommended for continuous use without extra cooling. Switching Frequency: Up to 1.5MHz (allows for a very small module size). Conversion Efficiency: Up to 96%. 🛠️ How to Use the HW-133-v1.0 Identify Pins: Locate the four solder pads: : Connect your power source here (e.g., a 12V battery). OUT+ / OUT-

: By offering a unique combination of features, Hw-133-v1.0 could pave the way for new product categories or enhance existing ones.

resistor) during calibration to ensure the voltage remains stable under load. Common Applications Due to its size, it is widely used in: The Hw-133-v1

: Providing efficient power to sensors in sealed outdoor enclosures. DIY Arduino/Raspberry Pi Projects : Often replacing bulkier LM2596-based modules due to its smaller size and lower power waste. step-by-step instructions
