I know some people from Amrita Vishwa Vidyapeetham so I think I can give you some idea about it.

M.Tech in Embedded Systems is a great course. As far as the choice between Bangalore and Coimbatore campuses is concerned, then without any doubt, Coimbatore campus is better between the two. Here are some details about the campuses.

Coimbatore Campus:

• This course is offered by the Electrical and Electronics department. So if you are an electrical graduate, then it is better for you.
• The department has very good lab facilities. There are various development boards and robotic kits which will help you increase your skills.
• The faculty are very helpful and will help in every way both academically as well as publishing in your journals.

Bangalore Campus:

• Here the course is offered by the Computer Science department. So if you are a CS graduate, then it is for you.
• The labs, teaching experience, facilities, research opportunities, and exposure to the industry are also very good.

Considering all the points and knowing that Coimbatore is the original and the oldest campus of the two, the preference of the campuses should be Coimbatore.
