High quality synchronous DC-DC buck converter with output voltage and current control. PWM controller is LTC1625, fully operational from ~4 to 36 V. Output voltage/current sense amplifier is LM358, powered from LTC1625 internal 5.2V regulator. Top/bottom switches are two pairs of RU3560 40V 50A, 13-18 mOhm MOSFETs. Have tested it at 5 and 12 V input, 1.5 to 8 V 1 to 5 A output and found it much more efficient than cheaper XL4016-based converters. For currents higher than 8 A a blow air cooling may be needed. Minimum output current set must be something of 500 mA, depending of current shunt and opamp. The board is of good design and neatly assembled, with reverse-polarity protection for input. Low ESR capacitor at output has MLCC shunt in parallel, while input capacitor does not.
Overall quality looks good. The seller is also recommended. Five stars
