Bus Masters

The 1-wire adapters are the interface between the computer and the 1-wire bus. In 1-wire lingo, they are called bus masters.

How to Choose?

  1. What ports are available?
  2. Do you want to offload processing from your CPU?
  3. Do you need advanced bus electrical control (overdrive, active pullup, echo cancelling, logical partitioning)?
