Is a bill of materials available, or specifically, a part number for the optional coin cell holder?
Hello William, you can use Keystone - 3003 .
Thanks Alberto!
if you are going to use the battery holder please add some solder to the battery center ground pad before you place the holder to ensure the battery makes good contact with the pad.
I was wondering about that, re: the solder mask.
yes the solder mask is higher than the bare pad. =)
