Motor Driver Board Control Shield Module for Arduin UNO, Arduin Mega 2560

1. Scope of application: Suitable for Arduin beginners, Arduin experimental equipment platform, Arduin interactive electronics, Arduin robots, etc.
2. Advantages: Many functions, easy operation, powerful driver library support and function updates.
3. Disadvantages: It takes up a lot of I/O and has low power when driving four motors at the same time (compared to the version with less Arduin I/O).
4. It can drive 4-channel DC motors or 2-channel stepper motors and also drive 2-channel servos. It supports Arduin UNO and Arduin Mega 2560.
5. This is a commonly used DC motor drive module, using the 293D chip small current DC motor drive chip. The pins are made Arduin compatible, which also facilitates enthusiasts to quickly develop based on Arduin.
6. 2 5V servo motor (servo) ports connected to Arduin's high-resolution and high-precision timer - no jitter!
7. Up to 4 bidirectional DC motors and 4-channel PWM speed regulation (approximately 0.5% resolution)
8. Forward and reverse control of up to 2 stepper motors, single/double step control, staggered or micro-stepping and rotation angle control.
9. 4-way H-bridge: Each bridge of the L293D chip provides .0.6A (peak 1.2A) current and has thermal power-off protection, 4.5V to 36V.
10. The pull-down resistor ensures that the motor remains stopped when powered on.
11. Large terminal terminal block makes wiring easier (10 - 22AWG) and power supply.
12. With Arduin reset button.
13. 2 large terminal external power supply terminal blocks ensure the separation of logic and motor drive power.
14. Compatible with Mega, Diecimila, & Duemilanove.
