Excellent Device, varit well, but you need to refine (strengthen the tracks with a single-core copper cable, for logic to output a separate food). The case is transparent, do not forget to shoot matte plates! In the photo, the peak current is 5 mode (400A, but this is a very weak battery for me), on the first mode of current 260A)

Before you strengthen-check how it works! I added a transistor, used 2 x 12awg on each line in quality test wires and reinforced the 3x1.5.5mm wire on one side: Recorded from a separate BP. The power part from the car battery, just the signs pressed. Native screws replaced with hexagon. All terminals are missing

I thought that I ordered only a fee ("v7 Blue Board"), but this is a complete set with wires. If anyone expects to solder on the reverse side of the transistors, it is better to think about it a hundred times. A simple soldering iron does not do this, you need good equipment. I didn't get it.

Excellent thing, so far I just assembled, did not Weld. I did not understand why the slots in the case for the cooler, the distance from the case to the board is exactly 10mm, which is equal to the thickness of the cooler, and the MOS the board has 5 V power supply)

Excellent. I'm going to collect as shown in yutuba, with a separate power supply. Buttons included are two and both workers. The wires are too short, we add, increase the section. In the garage is now cool, we will transfer experiments to the spring.
