More commonly known as the Beaglebone Black chip.

There are two main streams for this one:

A bare AM3358 (or similar):

- $14-25 in singles

- Difficult to design with

- Expensive boards - smaller than 5/5 process that most Chinese boardhouses are capable with

- Very well supported. Second only to Raspberry Pi itself

The Octavo:

- $60-70

- Less cool

- Way easier to design into a PCB

- Less demanding board process
