You will think that mini-computer enthusiasts will have a complete world, considering that you have an alternative: Arudino, raspberry π, beaglebone or even Intel's NUC. This does not prevent solidrun, which is a great time to release the HummingBoard as a more powerful alternative to raspberry π.
Built on the same platform, the HummingBoard promises faster silicon (1GHz arm v7vs.700mhz arm v6), while meeting the same third-party protocol as its education center counterpart.
It also allows switching your CPU and memory modules, and you should take some more steps. The basic configuration of 512mb RAM will cost $45, the power adapter will cost $10, and the model with the highest specifications of 1GB of RAM and faster chips will cost $100.
