Want to switch from Backend developement to Iot/embedded development? Is it a good move ?

I'm a backend developer with 3 yoe. Since childhood I was always passionate about electronics , embedded systems , robotics. I'm good at my current job but it doesn't satisfy me to the core.

My BE degree is in CSE. How can I switch to these kind of roles ? Do i need to do masters or i can upskill and switch ? Will I be considered as a fresher ?

Is it a good move in terms of career growth and pay ?

Please help me out fellow engineers !
