25 / 41 page ![]() Hardware and mechanical equipments AN2350 25/41 Figure 18. Driver board schematic (page 2) To avoid electromagnetic interference, all the signals have been shielded. For this reason an interface board with three 26 pin female shielded connectors has been developed, in order to be plugged in the male connectors of the SDK-ST10F276 board. The schematic of the interface board is shown below. 5 5 4 4 3 3 2 2 1 1 D D C C B B A A CW CW t=150us CW t=150us CW t=150us N.C.
