The TI PRU Cape is a BeagleBone Black add-on board that allows users get to know TI’s powerful Programmable Real-Time Unit (PRU) core and basic functionality.  The PRU is a low-latency microcontroller subsystem integrated in the Sitara AM335x and AM437x family of devices.  The PRU core is optimized for deterministic, real-time processing, direct access to I/Os and ultra-low-latency requirements.  It includes LEDs and push buttons for GPIO, audio, and a temp sensor.  Together the BeagleBone Black and PRUCAPE are an ideal EVM solution to begin PRU development on the Sitara platform.

  • BeagleBone and BeagleBone Black compatible plug-in board (“cape”)
  • Quick development and evaluation of the PRU integrated in Sitara processors
  • Leverages sample code included in the TI Linux Software Development Kit
  • The PRU core is optimized for deterministic, real-time processing, direct access to I/Os and ultra-low-latency requirements
