Hi Robert,

I have BBB from different vendors, and I do remember that I've
purchased the Element14 version at some point. However, I've messed

are the most probably right, but still I cannot confirm the origin.

Attached here is U7. It says M67E. 24AA32A/24LC32A datasheet page 14
says that it should be 24LC32AI.
