The L293D driver ICs can become hot during continuous operation near the 600mA limit. Stick small aluminum heatsinks onto the center of the chips to prevent thermal shutdown.
The is a popular, budget-friendly expansion board for Arduino [1]. It allows you to drive multiple DC motors, stepper motors, and servos simultaneously [1]. This shield is a direct clone of the classic Adafruit Motor Shield V1, relying on two L293D push-pull driver chips and a 74HCT595 shift register [1]. hw 130 motor control shield for arduino datasheet free
Built-in thermal shutdown and internal ESD protection. Reset Button: Onboard button for Arduino system reset. Pinout and Hardware Configuration The L293D driver ICs can become hot during
The HW-130 shield plugs directly on top of an Arduino Uno or Mega. It breaks out connections into several screw terminals and male header pins. Motor Connections Screw terminals for DC motors. M1 + M2: Five-terminal block used for Stepper Motor 1. M3 + M4: Five-terminal block used for Stepper Motor 2. It allows you to drive multiple DC motors,
The HW-130 shield is designed to plug directly onto an Arduino Uno, Mega, or Leonardo. It offloads the high-current demands of driving motors from the Arduino’s microcontroller to dedicated driver chips. Key Specifications: 2 x L293D Dual H-Bridge motor drivers.
Remove the physical plastic jumper pin next to the external power terminal block [1].
