2.2 Connections
Figure 2-1. MC300 with device board, connector details and prototype board fitted .
2.2.1 Device board connector
The MC300 driver board can directly connect to an AVR device board. This is
accomplished b y a horizontal female 0.1” pin header connector located on the left
side of the board, shown in Figure 2-1.
The device board interface on MC300 connector is split into four eight-pin connectors.
Electric schematics and mechanical specifications are shown in Figure 2-2 and
signal description in Table 2-2.
The connector s are mounted on the same 0 .1” grid. The g rid is positioned so the
connectors will f it an angled pin header on a prototype Vero-boar d, shown in Figure
2-1.
2.2.2 Power and motor connectors
The board has two power connectors located on the top, one 4 pin 3.81mm connector
(J3) and one DC-jack (J5) with 2.0mm center tap. J3 allows for separate power inputs
to Vin and Vm, w hile J5 powers both Vin and Vm via diodes. Refer to chapter 4.1 for
more details.
The motor connector (J7), a 10 pin 3.81mm con nector, is found on the lower right
side of the board. Signals and voltages associated with t he motor are easy accessible
on the pin row (J6) above the motor conn ector. Refer t o the schematics for signals
and pinout on J6 and J7.
