An expansion board for multiple pandora models

[Binky]

Based on the openmokast project and the way old meccano sets could be upgraded by buying expansion kits I would like to suggest the following:

One P2 model with slightly fewer, or the same, features as the P1 - at a somewhat lower cost


Another model with an expantion layer containing a extra PCB with other fun stuff on it:


Model A:

• whatever SOC/screen (irrelevant here)
  
• L1/R1
  
• microUSB otg
  
• one full USB port
  
• One internal Micro/mini SD slot (boot from this)
  
• One external SDXC slot
  
• headphones out
  
• one type of TV-out connector
  
• 3Ah battery
  
• reduced height keyboard etc
  
• Bluetooth
  
• Wifi
  

Extra layer adds the following to make model B

• Broadcast radio recivers (DVB/DAB/FM)
  
• GPS/magnometer
  
• accelerometer/gyro
  
• HSPDA
  
• dedicated charging port
  
• USB hub
  
• external SDXC slot
  
• Audio Line-out
  
• L2/R2
  
• external, and internal USB ports
  
• other TV-out connectors
  
• easy access to GPIO pins externally
  
• buttons on the side for mapping to shortcuts
  
• space for either an internal USB dongle or 2, or an extra battery

i dont want model A because it doesnt have L/R2, i dont want model B because it doesnt have L/R1

Model B has:

• whatever SOC/screen (irrelevant here)
  
• L1/R1
  
• microUSB otg
  
• one full USB port
  
• One internal Micro/mini SD slot (boot from this)
  
• One external SDXC slot
  
• headphones out
  
• one type of TV-out connector
  
• 3Ah battery
  
• reduced height keyboard etc
  
• Bluetooth
  
• Wifi
  
• Broadcast radio recivers (DVB/DAB/FM)
  
• GPS/magnometer
  
• accelerometer/gyro
  
• HSPDA
  
• dedicated charging port
  
• USB hub
  
• external SDXC slot
  
• Audio Line-out
  
• L2/R2
  
• external, and internal USB ports
  
• other TV-out connectors
  
• easy access to GPIO pins externally
  
• buttons on the side for mapping to shortcuts
  
• space for either an internal USB dongle or 2, or an extra battery
  

(as you can guess from the lack of SOC, Screen, keyboard, what I labeled as model B was actually the contents of the expansion board )

Could the Wifi and BT be dropped from the model A, as they could be added by the user with a mini USB dongle?

Hey, isn't that a picture of a Freerunner!

It is indeed, with an openmokast expansion layer for internal USB devices

I like the idea of an expansion board but I would want it to be powered sepertatly I know that was already in there but I cannot stress this enough . Also I don't personally care for micro sd as I always lose the buggers .

Binky, please don't take this the wrong way. I do really like your imagination and wish to continue seeing your ideas. The more ideas the better! I do, on the other hand, sometimes think you want Pandora 2 to be a mobile suit gundam instead of a handheld.

^ _That_ is why there are more recent threads suggesting a wireless dock

I'm a little confused by the design. Also the reason behind it.
