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 46v,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. Specification: Chip: L298N Logic voltage: 5V Logic current 0mA-36mA Maximum power: 25W Drive voltage: 5V-35V Drive current: 2A(For each DC motor) Operating mode: Dual H-bridge driver (can drive 2 DC motors) Reason 1: Use L298N for Main Chip L298N is a kind of high voltage, high current motor driver chip. Features as high working voltage (maximum voltage up to 46V), large output current (instantaneous current up to 3A), continuous working current 2A and 25W of rated power. Having 15 pins as package. Two built-in H Birdge high voltage and large current full bridge drivers can be used to drive the DC motor and stepper motor, relay coil and so on. The chip can connects to external detecting resistor to give the variations to the control circuit. Using L298N Chip to drive the motor, the chip can drive a stepping motor or four phase stepping motor, and two DC motors as well. Using standard logic level signal control, it has two enable control ends. It permits or prohibites device having a logic power supply input without the impact of input signal, which enables the internal logic circuit part works at low voltage. Reason 2: Wide Application size: 43 x 43 x 27mm Material: PCB colour: red Package Contents: 2 x L298N Motor Drive Controller Board Module Only the above package content, other are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
