PRU Real-Time I/O Evaluation Reference Design

This reference design is a BeagleBone Black add-on board that allows users to explore TI's powerful Programmable Real-Time Unit (PRU) core and basic functionality. The PRU is a low-latency microcontroller subsystem integrated into Sitara's AM335x and AM437x family of devices. The PRU core is optimized for deterministic real-time processing, with direct access to I/O and ultra-low latency requirements. Featuring LEDs and buttons for GPIO, audio, temperature sensors, optional character display, and more, this add-on board provides schematics, bill of materials (BOM), design files, and design guides to allow designers to learn the basics of the PRU.
