acejas Posted June 23, 2016 Share Posted June 23, 2016 Hi Sascha (or anybody else) Earlier threads on forums state that the diode should be as close to the feedback device. Are there issues when having such a board as yours? ie solenoids are placed all around the cabinet Cheers Link to comment Share on other sites More sharing options...

Content Provider UncleSash Posted June 25, 2016 Author Content Provider Share Posted June 25, 2016 Hi Sascha (or anybody else) Earlier threads on forums state that the diode should be as close to the feedback device. Are there issues when having such a board as yours? ie solenoids are placed all around the cabinet Cheers Yes, You are right. The best is when the flyback diode is so close as possible to the coil. But my PCB should work. The wire length in the cabs are not so long. Link to comment Share on other sites More sharing options...
Content Provider UncleSash Posted June 25, 2016 Author Content Provider Share Posted June 25, 2016 And when you buy a PCB from me and it not works, you send the PCB back to me and you get your money back. And when it works, you have to make a review post with pictures!!! [emoji57] Link to comment Share on other sites More sharing options...
