Features: L298N as main chip, ST corporation production. Low heat,outstanding anti-interference performance. High working power to 46v,large current can reach 3A MAX and continue current is 2A, power to 25w. Can drive one 2-phase stepper motor, one stepper motor or two DC motors. Built-in 78M05,get power from drive power,however, when drive power over 12V, please use the external 5v power as power supply. Large capacity filter capacitance,afterflow protection diode, more stable and reliable. Specification: Double H bridge drive Chip: L298N (ST NEW) Logical voltage: 5V Drive voltage: 5V-35V Logical current: 0mA-36mA Drive current: 2A(MAX single bridge) Max power: 25W Size: Approx. 40 x 40 x 25mm Package includes: 1x L298N Stepper Motor Drive Module Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement. Sold by-Dadangjia
