Output Voltage: DC 0.8 V – 20 V (Adjustable via onboard potentiometer)
Max Output Current: 3 A
Peak Conversion Efficiency: 92% Output Ripple: Switching Frequency: 1.5 MHz (max) / 1 MHz (typical)
Operating Temperature: -45 ℃ to +85 ℃ Module Dimensions: 22 mm × 17 mm × 4 mm

Typical Applications
These versatile step-down modules are ideal for a wide range of electronics projects and professional applications, including:
Powering Arduino, Raspberry Pi, ESP32, and other development boards
Converting 24 V or 12 V to 5 V, 3.3 V, or 9 V for sensor arrays
Battery and solar panel voltage regulation
RC vehicles, drones, and model electronics
Automotive and marine 12 V / 24 V step-down circuits
Breadboard prototyping and custom PCB designs

Important Safety & Usage Notes
Please follow these guidelines to ensure safe operation and maximize module lifespan:
Do not reverse polarity. Reversing the positive (+) and negative (-) input terminals will cause permanent damage to the module.
Avoid light-load or no-load operation. Do not run the module below 10% of its rated output power or without a connected load, as this may lead to instability or component damage.
Always preset the voltage. Use the onboard trim potentiometer to adjust and verify the output voltage with a multimeter before connecting sensitive devices.
Ensure adequate heat dissipation when operating continuously near the 3 A current limit.
