⚡ Quick Start Guide & Important Tips

🔹 What It Does & What You Need
✅ This module does:

Boosts DC 2-24V to 2-28V adjustable output

Up to 2A output current

Short circuit and overheat protection
❌ This module does NOT: Step down (boost only), constant current output
🔧 You will need: DC power supply (2-24V), multimeter, load device
📦 Package includes: Boost module × (as per SKU)

🔹 Wiring & Usage

⚠️ Important:

Input voltage: 2-24V only. Exceeding 24V may damage chip.

Input must be lower than output (boost converter).

Heat: Module gets warm at high power – add heatsink or ensure ventilation.

Polarity: Reversing input/output may damage module.

Adjustment: Turn potentiometer fully counterclockwise before powering on, then slowly increase.

🔹 Output Current Reference

🔹 Common Questions

❓ Why can’t I reach 28V output?
Input voltage must be at least 5V for 28V output. Low input limits output.

❓ Module getting hot?
Normal at high power. Reduce load or add heatsink.

❓ Can I use it as a battery charger?
Not recommended – constant voltage output. Use a dedicated charger.

❓ SX1308 vs MT3608?
Compatible – same performance. MT3608 is common, SX1308 is equivalent.

❓ First time adjustment?
Turn potentiometer fully counterclockwise before powering on, then adjust slowly.
