Good morning Kwakisaki,
I couldn't work it yesterday but today i checked all the connections after studying the manual you sent which now brought me a new problem: after powering the board according to the pin assignment contained in the manual you sent, the board seems to keep the outputs on at all times, my first thought was that the board is not in good condition, or could it be some configuration/function it has?
Mind you I am only interested in the output.
