Overview
Arduino is a great starting point for electronics, and with a motor shield it can also be a nice
tidy platform for robotics and mechatronics. Here is a design for a full-featured motor shield
that will be able to power many simple to medium-complexity projects.
2 co nnectio ns fo r 5V 'ho bby' servo s
connected to the Arduino's high-resolution
dedicated timer - no jitter!
Up to 4 bi-directio nal DC
motors with individual 8-bit speed selection (so, about
0.5% resolution)
Up to 2 stepper mo to rs
(unipolar or bipolar) with single coil, double coil,
interleaved or micro-stepping.
4 H-Bridges: L293D chipset provides 0.6A per bridge (1.2A peak) with thermal
shutdown protection, 4.5V to 25V
Pull down resistors keep motors disabled during power-up
Big terminal block connectors to easily hook up wires (10-22AWG) and power
Arduino reset button brought up top
2-pin terminal block to connect external power, for seperate logic/motor supplies
Tested compatible with Mega, Diecimila, & Duemilanove
Full kit available for purchase from the Adafruit shop.
