Hi,
I tried to build and flash WLED for the Athom GU10 bulbs and bricked it. 
I used [env:athom7w], after some research I guess, I should have chosen [env:athom15w]. Before I give it another try, I would be nice if someone could help me out here and confirm that [env:athom15w] is correct.
Greetings
