Arduino Mini

Projects General Guidance

I want an Arduino to use with my Raspberry Pi. I was going to get a Nano but was advised that it required 5V to run it and the Pi only outputs 3.3V which is compatible with the Nano. I only want (at the moment) to play about with relays, motors etc. Would the Mini be a good choice. I am a complete beginner with Arduino but not with electronics. Any help would be appreciated.

Thanks

You are planning to power the Arduino from the Pi?
3.3V/8MHz Promini would be fine - connect the 3.3V to the VCC pin, and Gnd to Gnd.
Rx to Tx and Tx to Rx for Serial comm's.
