A boosterpack-compatible board for pfpp project.
This board holds a battery-backup'ed precision RTCC. It's main duty is to keep the time of the day and manage alarms that are set for feeding your pet.
on top of an RTCC, it also holds a MicroSD card cage, and a TB6612 motor controller. The MicroSD card can be used for logging events. The motor controller is used to activate the feeder.
This project was originally built for the EK-TM4C129EXL development board, on boosterpack2 location. It should work on any BoosterPack-compatible interface.
GPIO match for various development boards.
