The MC300 driver board can directly connect to an AVR device board. This is
accomplished by 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
signal description in Table 2-2.
The connectors are mounted on the same 0.1” grid. The grid is positioned so the
connectors will fit an angled pin header on a prototype Vero-board, shown in Figure
2-1.
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, while 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 connector, is found on the lower right
side of the board. Signals and voltages associated with the motor are easy accessible
on the pin row (J6) above the motor connector. Refer to the schematics for signals
and pinout on J6 and J7.
