Well I've been running numbers all evening (man I hate math) and it looks like the max current of the 17mm version will be around 2.2A, it's going to be limited by the power the 1206's can dissipate, I'm upgrading the 20mm version to 2512's and it shouldnt have a problem going to the full 4.2 the 2502 FET's can do. Kind of a bummer about the 17mm with the smaller 1206's but thats near max current for color XP-E2's and that is max current for an XML color. another option for multi emitter builds is to not run the parts on the white channel if you wanted it more powerful but were happy with the 2.25 to your color XP-E2's and run the white PWM trace to either a 7135 slave board or a MCUless FET driver.So as it stands the 17mm version is ready to order, the 20 mm version has the resistors replaced in the .sch and therefore on the board but I havent yet got them placed.Also got some other on topic news, There is a FW out there (non open source but the guy that has it let me see it) for a RGBW driver controlled only by power cycle, no e-switch required that runs the 12f617 (to date the only PIC uC I've actually connected to) All I've got to do is mod it to use RGB instead of white and I can make my S6 triple into a RGB light!
