What is BeagleBone Black?
The BeagleBone Black is a low-cost, community-supported development platform featuring an AM335x 1GHz ARM Cortex-A8 processor. It runs full-featured Linux distributions and offers extensive expansion capabilities through dual 46-pin headers. Designed for hobbyists, educators, and embedded developers, the board integrates 512MB of DDR3 RAM and 4GB of on-board eMMC flash storage preloaded with Debian. Its unique Programmable Real-Time Unit (PRU) subsystems allow for deterministic, low-latency real-time I/O operations.
