DollaTek DPS3012 30V 12A Constant Voltage Current Step-Down Power Supply Module Buck Voltage Converter Voltmeter

Clear and easy to use display.Control via the USB is nice and easy to implement and works well.Output power smooth and reliable.

Good metal case , not to big, nice size

Works well, very useful. Requires some skill to build. The fan is annoying as it is on all the time, unnecessarily at low power settings.

Apologies it's my mistake I didn't read the description it's actually says no lcd and no a main board my bad.

Unable to use or test as delivered items did not match description advertised as it wasn't clear that this was only part of a working unit and the complete unit would have cost another £35. Having part of a unit is of little use to anyone.

It's implied that the unit can handle both Bluetooth and USB communication at the same time, and while it comes with both boards only one can be plugged in and used at a time, not both which is frustrating and should have been made much clearer, I guess it could be hacked with a switch to switch between them easily and it would be nice if the kit at least came with such a changeover board/switch pre-assembled with leads (the kit only comes with one comms lead so to use a switch you would have to make/obtain another lead) also while installation of the comms boards is fairly straightforward it's not well covered in the manual.

The kit includes everything you need to wire up the adjustable power supply (except a crimping tool to put the connectors onto the cable).The supplied red and black wires are really too short, you would have to be mm perfect in cutting lengths to not run out of cable.

No complaints about the product, but the box was made of thick plastic, this is not good, should have been a cardboard box
