Board Layout

The BQ76905EVM circuit module is a 2.175-inch × 4.4-inch 2-layer circuit card assembly. The BQ76905EVM is designed for easy assembly with cell connections on the left edge to a terminal block. Pack terminals are on the bottom edge using a terminal block. Wide trace areas are used reducing voltage drops on the high current paths. An on-board interface adapter with USB connector is located in the right lower corner.

See additional information in the configuration and operation sections of this document.
