1.4 Board variants
At the time of writing this document, AM3352-SOM is the only Olimex-made board featuring
Texas Instruments AM3352.
Other SOM boards that might be compared to functionality are: the well-supported A20-SOM, and
the new powerhouse RK3188-SOM.
Another Olimex board with close characteristics is A13-SOM board. The performance of Texas
Instrument's AM3352 and Allwinner's A13 is nearly identical. The two main differences are: the
A13 is cheaper; the AM3352 is documented much better. Another important point is that we
consider the A13 boards mature – many of the issues had already been resolved and the
performance is stable. For simpler command-line tasks A13-SOM might be the most suitable
choice.
