L298N Dual Motor Driver Board (H-Bridge)

  • Sale
  • Regular price $ 4.99


The L298N is a versatile motor driver used for controlling high powered motors with low voltage / low current microcontrollers.

Since it is an H-Bridge, it can drive the motor forward or backwards.

The L298N allows for voltages from 5V to 35V (24V max suggested) and is perfect for 12VDC robotic and R/C motors. It supports up to 2 amps, with a maximum power of 25 watts.

The board features heat sink, large capacitors, protection diodes, and ports for two motors.

Specifications

  • Voltage range: 5V to 35V
  • Maximum amperage for all channels combined: 2A
