Mining Algorithm: SHA-256, Minable Coins: Bitcoin (BTC), BitcoinCash (BCH), Acoin (ACOIN), Curecoin (CURE), Joulecoin (XJO), Unbreakable (UNB), Peercoin (PPC), Mark (DEM), Terracoin (TRC), BitcoinSV (BSV).
This listing is for the GekkoScience 2Pac USB stick bitcoin miner. This is a small-scale miner which requires USB power to operate - it cannot be run standalone. They're great learning tools and solo lottery miners. The 2Pac is not limited to Bitcoins only, but can mine any SHA256-based cryptocurrency.
The default operating frequency is 100MHz for 11GH/s, but as with everything GekkoScience makes, both the speed and core voltage are fully adjustable. Adjusting voltage requires a precision Philips screwdriver, but frequency is a simple software flag. 2Pacs will run from 50MHz (5.5GH) up to at least 350MHz (35.8GH/s) with a strong USB hub and adequate cooling.
Extra cooling is required for overclocking!
