From the project

A collection of circuit designs for various MCUs, not just Raspberry Pis relating to Model Railroading

This is a circuit board that supports a PocketBeagle board to manage a range of possible interlocking plants or other model railroad situations. It contains four stall motor drivers with point sense, four CT Coil type occupancy detectors, four Schmitt-Trigger inputs (for push buttons), four driver outputs, 8 GPIO pins in a 5x2 header, and 16 PWM LED drivers.
