which is the better one out of these two ( for an S2+ triple Build 3A )
Led4power website is down, they had nice linear drivers with lots of programming options. https://led4power.com/wp-content/uploads/2017/12/LD-4-datasheet-1.1.pdf(link is external)
Kaidomain is the only option I can find: http://kaidomain.com/Flashlight-(link is external)DIY-and-Tools/Flashlight-Drivers/BD39-17mm-2200mA-3V-9V-1-cell-or-2-cells-Buck-Driver-Board
