Motor drive module is ideal for use in battery-powered smart car, toy cars, robots. | Dual H-bridge motor driver, can drive two DC motors or a 4-wire two-phase stepper motor. | Supply voltage 2V -- 10V, can drive two DC motors or a 4-wire 2-phase stepper motors ,can achieve forward rotation or reverse rotation, it is possible to adjust the rotation speed. | Dual 1.5A * 2, the peak current to be 2.5A, built-in thermal protection circuit, do not be afraid motor stall burned, automatic recovery after the temperature dropped. | Use of imported original chip, built-in low on-resistance MOS switch, minimal heat, no heat sink, small size, low power consumption, is ideal for battery powered.

This Ir transmitter sensor module is directly launched by a single tube; | It requires waveform modulation through the program; | Pin Definitions: (1) Output (2) Vcc (3) GND; | Attention: The white smudge is not corrosion damage, it's flux, can wipe it off with a rag, does not affect the use of the module; | Widely used for infrared communication, infrared remote control, apply to a variety of platforms including 51/AVR/ARM;With signal indicating LED, easy to observe and debug.
