Specifications:

1. 2 connections for 5V ‘hobby’ servos connected to the Arduino’s high-resolution dedicated timer
2. 4 H-Bridges: L293D chipset provides 0.6A per bridge (1.2A peak) with thermal shutdown protection, internal kickback protection diodes.
3. Can run motors on 4.5VDC to 25VDC.
4. Up to 4 bi-directional DC motors with individual 8-bit speed selection (so, about 0.5% resolution)
5. Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil, or interleaved stepping.
6. Pull-down resistors keep motors disabled during power-up
7. Big terminal block connectors to easily hook up wires (18-26AWG) and power
8. Arduino reset button brought up top
9. 2-pin terminal block and jumper to connect external power, for separate logic/motor supplies
10. Tested compatible with Arduino Mega 1280 & 2560, Diecimila, Duemilanove, and UNO
