2 connections for 5V ‘hobby’ servos connected to the Arduino’s high-resolution dedicated timer 4 H-Bridges: L293D chip-set 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 (so, about 0.5% resolution) Up to 2 stepper motors (uni-polar or bipolar) with single coil, double coil, or interleaved stepping.
