Mini-WR
Introduction
By push the fibre-optic SFP connector to its carrier board, Mini-WR makes itself the SMALLEST White Rabbit Node implementation and gives flexibility for connector/panel arrangement on the carrier board.
As a plug&play module, Mini-WR requires no(few) WR knowledge to operate and ease the integration of White Rabbit functionality on custom system,
