title: Embedded System: Which platform or board?
body: <p>I want to build a portable system / device for processing guitar effects (own pod)</p>
  
  <p>I need:
  touchscreen (as main input)
  ssd / sd card or other?
  intel pentium i3,5,7? (needs power for processing realtime effects
  network (bluetooth, wlan, ethernet ...) (for control, configuration ...)
  audio input / output (for the guitar / recording ...)
  linux
  transportable (no big power supply, with rechargeable batteries and also usb and normal power supply)</p>
  
  <p>i would write the application running on the system with c++ in qt</p>
  
  <p>I saw many interesting boards like arduino, beagleboard, hawkboard and some mini / micro itx embedded systems, but now i dont know anymore which one i should choose</p>
  
  <p>should also be easy to develope for and not so expensive</p>
