Jumper Present: Connects Arduino’s 5V rail to the motor power line. Only use this if your motors require less than 5V and draw very low current.
The shield's functionality is built around three primary integrated circuits: Dual L293D Motor Drivers hw 130 motor control shield for arduino datasheet
Typical performance and limitations
74HC595 8-bit Serial Shift Register (used to expand pins for motor direction). Output Channels: 4 bi-directional DC motors with individual 8-bit speed selection. 2 stepper motors (unipolar or bipolar). 2 Servo ports connected to Arduino’s high-resolution timers. Output Current: 0.6A per bridge (1.2A peak). Voltage Range: Jumper Present: Connects Arduino’s 5V rail to the
Key onboard components:
Supports motor power from 4.5V to 25V (some versions rated up to 36V). Logic Voltage: Standard 5V operation. Dimensions: Approximately 69mm x 53mm x 14.3mm. 5.imimg.com Drive Capabilities DC Motors: Output Channels: 4 bi-directional DC motors with individual
