The Beaglebones, including this one, use the AM335X chip, which includes two PRU units on die. These are microcontrollers that have access to the same memory as the main ARM cores, and an API to share data.

This allows for real-time-ish use cases that the Raspberry PI can't handle well. Low latency audio, driving large LED matrix boards, high speed input sampling, etc.

So it's not quite the same market. $25 in this space is rock bottom pricing.

> tyingq: The pair of PRUs in the Beaglebone black is a large part of it.

CNC machining and 3D printing is one use case where Beaglebones are very common.

This LinuxCNC fork supports it natively: http://www.machinekit.io/
