Photosbykev Posted September 10, 2018 Report Share Posted September 10, 2018 Hi, probably old news for the experienced Dome users but I've just found a link to a 3W LED mounted on a pcb which only requires power and one control pin. Rather than using MOSFETs etc etc a dome could be built using only one LED driver board with all the LEDS wired in parallel and a single control wire for each LED https://www.ebay.co.uk/itm/3W-High-Power-KEYES-LED-Module-With-PCB-Chassis-For-Arduino-STM32-AVR-UK/232870808490?ssPageName=STRK%3AMEBIDX%3AIT&var=532402693460&_trksid=p2057872.m2749.l2649 I've ordered a handful to have a play with Kev Quote Link to comment Share on other sites More sharing options...
