Roll over image to zoom in

The RD33774PDSTEVB is a distributed cell monitoring unit (CMU) reference design with electrical transport protocol link (ETPL) communication. It is ideal for rapid prototyping of a high-voltage battery management system (HVBMS) hardware and software. This board contains one MC33774 analog front end (AFE). Several units of this board can be connected to the same daisy chain.
