Features: 1. Made of high quality material, durable and long service life. 2. Small internal resistance, the value is 140 milliohms 3. Powered by 6.5V~24V working voltage which can provide stable performance. 4. Low current and PWM frequency, it can work between -40℃-125℃ 5. Suitable for 4 channels output robot car stepper motor. Specification: Condition: 100% Brand New Working Voltage: 6.5V~24V Power Supply Internal Resistance: 140 milliohms PWM Frequency: <10KHZ Drive High Current: 5A Temperature Range: -40℃ ~ 125℃ Package List: 1 * Motor Drive Module Note: 1. When connecting, each pin has a corresponding identity, and you can check it carefully. Do not reverse the positive and negative terminals of the power supply. 2. Do not exceed the large operating current and operating voltage of the driver while it is working. 3. When the driver is working, pay attention to the heat of the mc33886 chip. If the fever is very serious, please stop working. 4, (FS1\\FS2) fault status indication. Under normal circumstances, the output 0 is low. When the motor is commutating, the transient current of the loop is relatively large, which exceeds the overcurrent protection threshold of the chip, and the flip output 1 is high. When the FS continues to level down, please power off immediately to avoid chip burnout. 1、Made of high quality material, durable and long service life. 2、Small internal resistance, the value is 140 milliohms 3、Powered by 6.5V~24V working voltage which can provide stable performance. 4、Low current and PWM frequency, it can work between -40℃-125℃ 5、Suitable for 4 channels output robot car stepper motor.
