A distributed auxiliary hub for a portable electronic device is disclosed. The distributed auxiliary hub, located on a stacked circuit assembly, can distribute electrical signals to multiple different destinations. The distributed auxiliary hub is displaced and separate from a main logic board, and as a result, can provide supplemental functions. Although the distributed auxiliary hub is electrically coupled to the main logic board, the distributed auxiliary hub includes dedicated integrated circuits responsible for executing functions related to battery charging and powering of electronic components (e.g., haptic feedback module, speaker module, etc.). As a result, the distributed auxiliary hub, when executing these aforementioned functions, is not reliant upon the main logic board to transmit electrical current to the battery and/or electronic components. The distributed auxiliary hub, when electrically coupled to an external resource, is capable of directly transmitting electrical current to electronic components.
