Product Description
| It is a good introduction to electronic production, and with the motor expansion board can be a good robotDevelopment platform. Here is a full-featured motor expansion board that can drive a variety of simple to slightly complex projects. This is a commonly used DC motor drive module, using 293DChip Small current DC motor drive chip. The pins are made compatible, which also facilitates quick and easy-to-use development by enthusiasts。 * 2 x 5V servo motor (servo) ports connect to Arduin's high-resolution high-precision timer - no jitter! * Up to 4 bidirectional DC motors and 4 PWM speed regulation (approx. 0.5% resolution) * Up to 2 stepper motors forward and reverse control, single/double step control, staggered or microstep and rotation angle control. * 4 H-bridges: The L293D chip provides .0.6A (peak 1.2A) current per bridge and has thermal power-loss protection, 4.5V to 36V. * Pull-down resistance ensures that the motor remains stationary when powered on. * Large terminal blocks make wiring easier (10 - 22AWG) and power. * With Arduino reset button. * 2 large terminal external power terminals to ensure the separation of logic and motor drive power supply. * Compatible with Mega, Diecimila, & Duemilanove. *Download easy-to-use Arduino software libraries for quick project development Scope of application: Arduin beginners, Arduin experimental equipment platform, Arduin interactive electronics, Arduin robots, etc. Features: Many functions, easy operation, powerful driver library support and function updates. Disadvantages: I/O usage is high When driving four motors at the same time (compared to the version with less Arduin I/O), the power is low. It can drive 4 DC motors or 2 stepper motors as well as 2 servos, supporting the latest Arduin UNO, Arduin Mega 2560 You can use it like this: Drive four DC motors and two servos Drive two DC motors and one stepper motor and two servos Drive two stepper motors and two servos |
