Because original manufacturer documentation for clone modules can be fragmented, this document serves as a complete, consolidated datasheet and deployment guide. It delivers better, clearer technical definitions, accurate pin mappings, and concrete implementation examples to maximize the performance of your robotics hardware. 1. Core Technical Specifications
void setup() // Set all control pins to outputs pinMode(ENA, OUTPUT); pinMode(IN1, OUTPUT); pinMode(IN2, OUTPUT);
Up to (5V) connected to the Arduino’s dedicated timers.
Built-in thermal shutdown and internal kickback protection diodes. 2. Pin Layout & Functions
The is a popular, low-cost expansion board for the Arduino Uno and Mega, designed to drive a variety of motors simultaneously with minimal wiring. It is technically identical to the classic Adafruit Motor Shield v1 design and is powered by dual L293D dual-channel H-bridge drivers. Technical Specifications
Because it uses a shift register, most motor control signals are handled internally. However, certain Arduino pins are "reserved" when the shield is plugged in. Arduino Pins Used Description 4, 7, 8, 12 Communicates with the 74HC595 latch. PWM Speed (DC) 3, 5, 6, 11 Controls motor speed via PWM. Servo 1 Digital Pin 9 Connects to the standard Servo 1 header. Servo 2 Digital Pin 10 Connects to the standard Servo 2 header. Analog Inputs Generally free for sensors or extra I/O. 3. Power Connection (Critical) L293D Based Arduino Motor Shield
