Concept
An inductor stores energy then dumps it at a higher voltage (boost topology).
A little theory
Switching ~1 MHz. Efficiency ~80–90% if not in dropout. Set Vout with the pot + DMM before connecting load. In the classroom, treat MT3608 Boost Converter Module as a beginner part using Adjustable DC-DC boost. Typical India street price is about ₹30–₹80. Always verify voltage and pin labels on your exact module — silk screens vary across clones. Start with a datasheet or trusted learn guide, power the part correctly, share GND with the MCU, and test with a simple blink/read sketch before building the full project. Measure voltages with a multimeter when something fails, and keep actuator current off the MCU regulator.
How it works in a project
Li-ion → IN, DMM on OUT, trim pot, then connect 5 V device.
Classroom & project use
- Battery → 5 V
- LED strings
- 12 V from 5 V (light load)
Buying in India
Precautions
- Set voltage before connecting
- Not for high-current motors
