H-bridge dual channel type driver, drive voltage is 5V to 35V, drive current is 2A. There is a big heat sink on board for better heat dissipation. Convenient to use, designed with screw terminals for easy wiring. It is normally used for driving stepping motor on smart cars or robots. Specifications: Work Mode: H bridge drive (dual-channel) Main Control Chip: L298N Logic Voltage: 5V Drive Voltage: 5V-35V Logic Current: 0mA-36mA Drive Current: 2A(MAX single-bridge) Storage Temperature: -20 to +135 Max. Power: 25W Size: 4.5*4.5*2.8cm/1.7*1.7*1.1in Weight: 27g(approx.) Notes: 1. When driving voltage is 7V-12V, it can use on-board 5V logic voltage as power supply; when using on-board 5V as power supply, do not input voltage on the +5V terminal,however,it can lead to 5V voltage for external use. (this is a regular application) 2. When driving voltage is higher than 12V and less than or equal to 24V, for example, to drive motor with a rated voltage of 18V, first of all, you must pull out the jumper of on-board 5V output enable.Then connect 5V to the 5V output port external. 5V enable is a control signal with a 5V level; when the input signal is valid and power supply of motor drive module is normal, motor driver module outputs current. Otherwise, even if the power supply is normal, there is no current on motor. Package Includes: 1 x Motor Driver
