The Screwdriver uses 901 atomizers and 901 carts. The RN4075 atomizers will also work on any 901 connection. And you can use 510 carts on a 901 atomizer.
The Prodigy has adapters that let you use either a 901 or 801 atomizer and carts, which ever you prefer. 801 atomizer and carts are larger than the 901 atomizer and carts. I personally only like the 801 atomizer on a PV that provides 5V of power such as the Prodigy.
NOTE: I've been told that trog is providing an adapter for the 801 atomizer on the Screwdriver but I have not seen that myself.
