some questions regarding tinyduino

[mushimaru]

What software do we use to make it work?
is it open source? does it have a simulator to test the programs used for the circuits?
Can I connect it to raspberry pi hardware?

[Ben Rose]

TinyDuino is open source and software compatible with the Arduino Uno. We don't support any simulation software.

It can be connected to the Raspberry Pi through the USB shield.

Thanks,
Ben
