Arduino is an excellent starting point for electronics, and when paired with a motor shield, it becomes a clean and versatile platform for robotics and mechatronics projects. This full-featured motor shield is designed to power a wide range of simple to medium-complexity projects.
Features:
- Two dedicated 5V servo connections using Arduino’s high-resolution timers—ensuring jitter-free performance.
- Compatible with both Arduino UNO and Arduino Mega2560 boards.
- Supports up to 4 bi-directional DC motors with individual 8-bit speed control (~0.5% resolution).
- Can drive up to 2 stepper motors (unipolar or bipolar) with single-coil, double-coil, interleaved, or micro-stepping modes.
- Includes 4 H-Bridge drivers (L293D chipset) providing 0.6A per channel (1.2A peak) with thermal shutdown protection, operating from 4.5V to 12V.
- Pull-down resistors keep motors disabled during power-up for safety.
- Large terminal blocks for easy wiring (supports 10–22 AWG wires) and power connections.
- Arduino reset button accessible on top of the shield.
- 2-pin terminal block allows connection of an external power supply for separate logic and motor power.
