ARD-MD Arduino Servo/Stepper/Motor driver shield

Arduino Servo/Stepper/Motor driver shield

This is a full-featured motor shield that will be able to power many simple to medium-complexity projects.

Specifications:

2 connections for 5V 'hobby' servos connected to the Arduino's high-resolution dedicated timer

4 H-Bridges: L293D chipset provides 0.6A per bridge (1.2A peak) with thermal shutdown protection, internal kickback protection diodes.

Can run motors on 4.5VDC to 25VDC.

Up to 4 bi-directional DC motors with individual 8-bit speed selection (about 0.5% resolution)

Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil or interleaved stepping.

Resistors keep motors disabled during power-up

Big terminal block connectors to easily hook up wires (18-26AWG) and power

Arduino reset button brought up top

2-pin terminal block and jumper to connect external power, for separate logic/motor supplies
