Boost Converter Module
The Boost Converter Module is a compact, adjustable DC–DC step-up (boost) regulator designed to increase a lower input voltage to a higher output voltage. It is powered by the TPS61023 high-efficiency switching regulator from Texas Instruments, enabling reliable operation even from low-voltage sources such as LiPo batteries or solar panels.
A multi-turn potentiometer is included for precise output voltage adjustment, making the module ideal for battery-powered applications and compact embedded systems.
This makes it ideal for powering circuits from LiPo cells, USB power banks, solar panels, and other low-voltage sources in embedded projects and prototyping.

Quick Start
- Wire up
- Connect your lower-voltage source to VIN + and VIN –.
- Connect your load to VOUT + and VOUT – (common ground).
- Adjust output
- Use a small screwdriver to turn the potentiometer clockwise to raise voltage, counter-clockwise to lower.
- Monitor the output with a multimeter for precise setting.
- Test under load
- Apply a typical load and verify the voltage remains stable.
Tip: Always start with the potentiometer turned fully counter-clockwise (lowest voltage) before applying power. Then slowly dial up to your target voltage while monitoring with a meter.
