Using selected pins bring down just the pins of interest for Power, Data and general purpose GPIO like this... Since it is not likely that you are going to need all 40 of them !
A work in progress still but this is heading towards a picaxe controlling DC power up, then ttyAMA0 serial cmd line login, ssh via serial log off, shut down and DC power off back to uAmp standby for another few minutes or hours. Looks so far like this system should run for over a month or more like this.
But so far it all works nicely esp the uUSB Wifi dongle is neat. It logs things in a treat under latest Jessie. VNC now packaged with Jessie is Great too.
Will post some more adventures soon.
