All clear now!!! Thanks very much!!!pappyhttps://www.blogger.com/profile/00402710390588120356noreply@blogger.comtag:blogger.com,1999:blog-6100511197805579796.post-59244409032845603942018-05-07T20:39:56.675+02:002018-05-07T20:39:56.675+02:00I think you mean the led drive mosfet, you can use...I think you mean the led drive mosfet, you can use any NPN transistor, anything that can driver your led strip, mine was a TIP31, you can also use a N channel mosfet IRF640 or similar should do the job. Unluckly I've no layout for board.Davide Gironihttps://www.blogger.com/profile/16366076989473118278noreply@blogger.comtag:blogger.com,1999:blog-6100511197805579796.post-10433071769555376422018-05-07T05:36:30.313+02:002018-05-07T05:36:30.313+02:00I am trying to identify the transistor on the left...I am trying to identify the transistor on the left side. Is it an NPN mosfet?<br />Is there a printed layup for the board?<br /><br />thanks in advance for your answerspappyhttps://www.blogger.com/profile/00402710390588120356noreply@blogger.comtag:blogger.com,1999:blog-6100511197805579796.post-6075019791107089262018-05-06T16:14:07.293+02:002018-05-06T16:14:07.293+02:00Hello, you can write your questions here.Hello, you can write your questions here.Davide Gironihttps://www.blogger.com/profile/16366076989473118278noreply@blogger.comtag:blogger.com,1999:blog-6100511197805579796.post-27248250365841426322018-05-06T12:59:50.112+02:002018-05-06T12:59:50.112+02:00HI David,
