Input: DC 3 V to 40 V (input voltage must be 1.5 V higher than the output voltage, no boost)
Output: DC 1.5 V to 35 V voltage is continuously adjustable, maximum output current is 3 A
Steps: connect to power source, adjust the swirl button on the blue potentiometer and monitor voltage with multimeter to get the needed voltage (The factory have tested these at max voltage so they are very high by default, takes about 15-20 turns CCW before the voltage starts ramping down)
Features: all use SANYO solid-state capacitors, 36 u thickening circuit boards, high-Q inductance with LED indicator output
Size: 45 * 20 * 14 mm
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 and use a heat sink when for a long time working

I ordered four, all four are bad. The output voltage is the same as the input, and the potentiometer does not regulate. None of the four are good.
