Power board connector
The MC310 processor board can connect directly to a driver board (typically the MC300 power
board). This is accomplished by a horizontal male pin header connectors located on the right
side of the board, shown in .
The device board interface on MC310 connector is split into four eight-pin connectors. Electric
schematics and mechanical specifications are shown in and signal description in Table 2-1
Table 2-1.
