Abstract: A scalable electronic system is disclosed, comprised of multiple modular electronics clusters. Each modular electronics cluster comprises a receptacle for routing signals, and multiple resource cartridges for performing electronic functions. The resource cartridges are capable of being aligned in close proximity to the receptacle for communicating signals to and from the receptacle. In addition, the resource cartridges aligned with the receptacle are also capable of communicating with each other. The resource cartridges can be aligned or removed from alignment with the receptacle, without the need for additional electrical connection hardware. The receptacle includes at least one vertical transport channel for communicating with other modular electronics clusters.
