They are a not for profit organisation, backed by Chuck moore, Forth programming. They will probably build millions rather in thousands to achieve the target price. Already ARM11 based tablet backed by the Indian government is retailing for $50 (this one comes with out a screen so can easily have a saving of $15 equates to around $35 which is what they Board B costs)

This raspberry pie seems very interesting. As it runs on arm, ditching Linux and putting android on it shouldn't be to difficult. Connect it to ioio and through bt and use a tiuchscreen and it would be very small for my project. Interesting ideas

Gotcha
Well I was thinking more of using the Raspberry Pi as the android device and connecting it to the IOIO and a touchscreen, giving me, perhaps, a way to run Android without using a phone or the android x86 issues. Was just an idle thought but I might try it out. Hell it's only 25 bucks!

There are approximately 16 spare GPIOs, which are brought out to 1.27mm pin-strip. Voltage levels are 3v3. The connector choice is deliberately annoying to connect to directly; there is no over-voltage protection on the board so the intention is that people interested in serious interfacing will use an external board with buffers, level conversion and analog I/O rather than soldering directly onto the main board.
We also bring 2x I2C (3v3), I2S and an SPI (3v3) interface out to the same connector. We support one slave interface for I2C and one for SPI.
J2 (on the alpha boards) is a UART:
Pin | Function |
---|---|
1 | 3.3V |
2 | GND |
3 | TX |
4 | RX |
Kernel boot messages go to this UART at 115200bps.
We also bring out MIPI CSI-2 & DSI interfaces to a 1.27 mm pinstrip.
It seems that BeagleBone (http://beagleboard.org/bone) is more I/O-Pin-friendly but it's really cool to figure out a way keep IOIO's hardware low-cost.
I found that ARM itself is Cambridge based and that Cambridge University is the sponsor of Raspberry Pi. That's possibly why it is so cheap while using ARM11.
What if we make IOIO a usb device that can be plugged to Raspberry Pi (and to BeagleBoard/BeagleBone)?
