I expect boards to be in by the end of August 2014. After a quick overview to make sure all is well I will put them up for sale in the Makeatronics Store.
Once I get some time I will write up a detailed post on the hardware changes and the firmware running on it. Until then, here's the schematic if anybody wants to benefit from my experimenting.
Firmware is hosted on GitHub and licensed under the BSD 3 clause license.
