Features:
- DC to DC step-down module
- Thickened circuit boards
- Advanced solid-state capacitor
- Short circuit and over-temperature protection
- 100% tested, sealed in anti-static packaging

Kindly Note:
1. Input voltage must be 1.5 V higher than the output voltage, no boost
2. Do not reverse the input and output interface
3. Keep output under 2.5A (or 10W) and use a heat sink when for a long time working
4. The factory settings stay a high voltage, you may need to contrarotate the screw on blue potentiometer about 7-15 circles before the output voltage changes
