A DC-DC buck-boost converter module that accepts input voltages both higher and lower than the desired output, delivering a stable regulated output up to 5A. Two onboard potentiometers let you set the output voltage and maximum current independently.
Specifications
- Input Voltage – 6–35V DC
- Output Voltage – 1.0–33V DC (adjustable, can be higher or lower than input)
- Max Output Current – 5 A (adjustable from 0.05 A)
- Max Input Current – 7 A
- Conversion Efficiency – Up to 90% (measured at 12V in, 19V/2.5 A out)
- Adjustment – Voltage potentiometer + constant current potentiometer
- Size – 70 × 39 × 32 mm
Board Layout
- 1 – Input +
- 2 – Input −
- 3 – Constant current indicator LED
- 4 – Constant current adjustment potentiometer
- 5 – Output +

Jargon buster
Plain-language definitions for the technical terms used above.
- boost converter
- A boost converter is a switching power circuit that raises a lower input voltage to a higher output voltage. It is used when a device needs more voltage than its power source provides, for example running a 5 V sensor from a 3.3 V supply.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- potentiometer
- A variable resistor usually turned with a knob or shaft to create an adjustable electrical signal. It is often used for inputs such as volume, brightness or position, so it helps beginners learn how a microcontroller reads changing values.
