A super-handy mini-shield for the Cal-Eng Breadboarder series. Includes a 754410 (L293D compatible) dual-motor driver chip, I2C/Wire interface, and lots of extra I/O headers that use the standard hobby-servo pinout (-/+/signal).
Due to the differences in I2C/Wire pin definitions on the ATmega328 versus the ATmega32U4, a switch has been added to choose between the host MCU type. If only one kind of MCU will be used, two simple wire jumpers could be used instead.
It also features two I/O headers that are powered at battery voltage level (trace selectable) for high-speed servos, and other high-voltage uses.
The included socket or motor driver IC (depending on personal preference) and the I2C switch will need to be soldered in place.
As with most of our boards, we don't install or include headers or plugs, since the choice will vary greatly depending on the application and personal preferences. They are available (at a very low cost!) in the "Wires, Headers & Plugs" category.
