Horizontal Driver board

Here is a shot of a typical H driver board from the ECP series of sets. The trimpots shown below are not accessible to the user without using special and expensive PC extender boards, and these pots do not need adjustment as a normal maintenance routine anyways. There are no real user adjustments on this board, and failures are rare. Various versions of this board are not interchangeable between models, so make sure you order the right board if you need one.
