MCookie Upin27 Layout
Each stack-able mCookie module uses a set of 27 pins.
The pins usually connect to a Core module's pins. Core modules provide the pins. While other modules (non-Core modules) uses / consumes / occupies a pin. This enables the Core module to control, communicate, etc with the stacked module.
When a module uses a pin, it can be thought of as consuming or occupying a pin, which would make other modules attempting to use the same pin unusable. Although, care is taken to avoid conflicts with pin usage. Sometimes pin functionalities overlap between different modules.
Below is the chart which shows which pins are used for each specific module and can be used to find overlaps. If a conflict or overlap exist it is unlikely that both modules will be usable at the same time for a project. See section Known Conflicts to see a list of already known conflicts.
