The standard FocusLynx Controller hub can easliy be converted into a Dual-Focus Controller with the addition of the optional Second Stepper Driver board:

Featuring an easy-to-install board with a double row connector, the Second Stepper Driver pushes directly into the main FocusLynx control board.
