Works great!

This is a great little board with few components and it does exactly what it should.
I needed individual boards and cut the board in 4 with a sharp knife and the corner of a small file.
This is my first SMD soldering project. I used a small ended soldering iron. The inductor was difficult to solder and with patience the other components soldered fine. Once soldered the board was tested by driving a 10W LED from a 12V supply. The dimmable pin worked a treat.
My suggested improvements would be the ability to buy fully made boards and also separated boards.
The price of the board makes this is a fantastic value LED driver PSU, small and powerful.
It worked for me and I would recommend it.
