L293D motor driver H-bridge Shield Expansion Board Uno Mega L293 Arduino

L293D motor drive module expansion board motor board motor control shield Scope of application: Arduin beginners, Arduin experimental equipment platform, Arduin interactive electronics, Arduin robots, etc. Features: multiple functions, easy operation, powerful driver library support and function updates. Disadvantages: I/O takes up a lot of power in the case of driving four motors at the same time (compared to the version with less Arduin I/O), low power. It can drive 4 DC motors or 2 stepper motors and also drive 2 steering gears at the same time, supporting the latest Arduin UNO, Arduin Mega 2560 You can match it like this: drive four DC motors and two steering gears drive two DC motors and one stepping motor and two steering gears drive two stepping motors and two steering gears Arduin is a good introduction to electronic production , and with the motor expansion board, it can be a good robot development platform . Here is a full-featured motor expansion board that can drive various simple to slightly complex projects . This is a commonly used DC motor drive module, using 293D chip low current DC motor drive chip. The pins are made Arduin- compatible, which is also convenient for enthusiasts to develop quickly based on Arduin . * 2 5V servo motor (steering gear) ports connected to Arduin #39;s high-resolution high-precision timer - no jitter! * Up to 4 bidirectional DC motors and 4-way PWM speed regulation (about 0.5% resolution) * Up to 2 stepper motors for forward and reverse control, single/double step control, interleaved or microstep and rotation angle control. * 4-way H-bridge: L293D chip provides .0.6A (peak 1.2A) current per bridge and has thermal power-off protection, 4.5V to 36V. * A pull-down resistor ensures that the motor remains stopped at power-up. *Large terminal block for easier wiring (10 - 22AWG) and power. * With Arduin reset button. * 2 large terminal external power terminals to ensure the separation
