Since single-board computers became a thing, each year has seen the release of more and better SBCs than the preceding year; and 2015 did not disappoint. Now that we're well into 2016, here's our baseline of the best single-board computers. Peruse my list and let me know what you think. What improvements will 2016 bring? Note, this list is not meant to go over the minutiae of each board. We are just going to briefly touch on each one, tell you where to get one and give you an estimated selling price so that you can prepare your wallet. At the outro, I will opine on my choice of board and what factors shaped my decision.
The BeagleBone Green is the 6-layer successor to the BeagleBone Black. Priced at $39, BeagleBone Green is built around an AM335x 1GHz ARM Cortex-A8 processor. It comes with 512MB of DDR3 RAM and 4GB of on-board eMMC flash storage. Regrettably, it does not have a micro SD card slot. However, it does have 65 I/O pins, 7 of which can be configured as analog inputs. That is a heck of a lot of I/O.
The BBG has two cape headers, a cape being an expansion board. The headers let you attach capes to add functionality.
The biggest issue with the BBG is the fact that, unlike most other SBCs (including the BeagleBone Black), it does not come with a common display output. You are going to have to purchase an LCD cape or an HDMI cape to equip the BBG with a display output.
An argument could be made that a computer monitor would be needed instead of an LCD cape for any other SBC. While this is certainly true, I think that most people are likely to already have spare and/or unused monitors available to them.
