I purchased 2 Antminer s7 from Hong Kong and the hash boards have some device on them.  I am hoping someone can shed some light on what these are and what they are meant to do.

Hi Everyone.  Just joined the DGB mining community.  I have 2 Baikal 150MH/s mini miners that I have added to the pool.

Hopefully mining this coin will be fun.  I am new to mining and look forward to this.  

Does anyone know if there is any special configuration i need to do with these miners or just put the pool address . username, and password in?
