Posted by pete_c , 20 June 2017 · 850 views

It is a drawing only right now but easy to build these days and reasonably priced. Note that the Pine64 2Gb is larger than the RPi3.  It does have a built in RTC and it will run 64bit Ubuntu such that it runs circles around the RPi3 and sells for $29 USD with no case or power supply.   Baby steps here.... Testing a new little ligh...
