Finished this today, Cree XP-E2 RGB, 3000mAh Li-ion 3.7V, MHS V6 chassis (modified to fit), Spark 3 chip. I like the LED drivers on this board and it is easy to wire. It is large...so that is a disadvantage. Just thought I’d give it a try.Attachment 17377Attachment 17378Attachment 17379Attachment 17380Attachment 17381
