From the project
The Super Mikrobus Cape & Testbed is an industrial-grade expansion and validation platform engineered for the BeagleBone embedded computer ecosystem (BeagleBone Black, BeagleBone AI-64, BeagleY-AI, and PocketBeagle 2).
The Super Mikrobus Cape & Testbed is an industrial-grade expansion and validation platform engineered for the BeagleBone embedded computer ecosystem (BeagleBone Black, BeagleBone AI-64, BeagleY-AI, and PocketBeagle 2).
The platform expands the host processor's capabilities into 2 onboard mikroBUS™ sockets and 8 remote Shuttle Box testing interfaces via rugged 2x8 IDC headers. It provides deterministic, collision-free I2C addressing across 16 channels, bi-directional 3.3V/5V digital level translation, soft-start inrush current management, analog overvoltage clamping, and Cape ID autodetection.
