DANGI E SHOP Motor Driver Shield for Arduino (Multicolor) Micro Controller Board Electronic Hobby Kit

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, interleaved or micro-stepping. 4 h-bridges: l293d chipset provides 0.6a per bridge (1.2a peak) with thermal shutdown protection, 4.5v to12v pull down resistors keep motors disabled during power-up. The output enable of the l293d is directly connected to PWM outputs of the arduino. The motor shield is able to drive 2 servo motors, and has 8 half-bridge outputs for 2 stepper motors or 4 full h-bridge motor outputs or 8 half-bridge drivers, or a combination. The shield contains two l293d motor drivers and one 74hc595 shift register. The shift register expands 3 pins of the arduino to 8 pins to control the direction for the motor drivers.
