I think i have two boards left , but i have to look again .
Because it has 7135 chips on the back side , it requires a small spring or a brass button . Does Tool AA have enough space ?
I used one of these boards to make a 15mm fet driver too (single sided) , like djozz did with the 17mm version : comfychair-inspired quick+cheap+lazy single-sided 17DD FET-driver (poor man's nanjg92)
