Dual-channel H-bridge driver working mode creates higher working efficiency,L298N as main chip.Can drive one 2-phase stepper motor, one 4-phase stepper motor or two DC motors. | To avoid damage the voltage stabilizing chip, please use an external 5V logic supply when using more than 12V driving voltage | Use large-capacity filter capacitors and diode with freewheeling protection function, increasing reliability | High working power to 35v,large current can reach 3A MAX and continue current is 2A, power to 25w. | Large capacity filter capacitance,afterflow protection diode, more stable and reliable.
