Is it possible to set up an Antminer S3 using a a Raspberry Pi?
An Antminer S3 operates as a stand alone computer, so you need no controller. The device is configured and managed through a web browser interface, so you can configure it from any web browser.

The only downloaded tool from Bitmain for the Antimer that runs on a PC is their "IP address finder" app, and you can use any of hundreds of apps to discover the IP address of devices on your LAN, including Fing.
