46. Arduino half: An Arduino communicates to the Jolla via SPI and the back of the half is a breadboard with Arduino pins (ans SPI) broken out to easily connect any kind of hardware to the phone. A great hobby electronics half. If the Arduino IDE can run on the Jolla you have a full electronics development platform in your pocket! OK - (no SPI)
If SPI would be preffered for some reason, there could be i2c to SPI bridge. Though I think Arduino has i2c too, so why not to use it.

There could be same kind of OH for Raspberry Pi also.
