Features: Brand new and high quality Large capacity filter capacity, more stable and reliable. This stepper motor driver is normally used to drive the stepper motor on car or robots. This driver board has strong driving ability, low temperature, strong anti-interference ability, double channel H-bridge driver operation modes for high operating efficiency H bridge double channel type driver, the unit voltage is between 5V and 35V, the frequency converter current is 2A. It can drive a 2-step stepper motor phases, one 4 phase stepper motor or two motor There is a large heat sink on board for better heat dissipation. Use large capacity filter and diode capacitors with protections function, increasing the reliability The stepper motor driver module is convenient to use, designed with screw terminals for easy wiring. Specifications: Material:ABS Main control chip: Working mode: H-bridge drive (two-way) Voltage: 5V Current: 0~36mA Driving voltage: 5~35V (it is recommended that the maximum use should not exceed 24V). If power is needed on the board, The power supply range is 7V~35V (it is recommended that the maximum use should not exceed 24V).
