LeMaker Bass Preview

Updated June 24, 2015 with newly released images and data from the LeMaker Bass product page.

According to an article published in IotWorld China,  LeMaker introduced three new products at the June 20 Maker Faire held in Shenzhen, China.

The LeMaker Bass resembles the 96boards.org HiKey eight core ARM board, but instead of an HiSilicon Kirin 6220 eight core ARM SOC, it uses a more modest Actions Semiconductor S900 quad core 64 bit processor.

Mind you, a four core 64 bit ARM based SOC is nothing to sneeze at!

It should also lead to a lower price than the HiKey board.

There is very little information available at this time about the Actions Semiconductor S900 – basically just their press release linked above – however as it is an A53 architecture chip, some more information could be gleaned from arm.com, and an article at cnx-software about the Bubblegum-64 development board from Actions Semiconductor.

I plan on updating this article as I receive more information – this will be another board I am looking forward to evaluating.
