Features Dual H Bridge: The dual H bridge motor driver can drive 2pcs DC motor or one 4 wire 2 phase step motor at the same time. 2.5Ax2 Driver: 2 way 2.5A, which is an enhanced version of 1.5A motor drive, making the motor control much more convenient. Safer Working: Anti common state conduction circuit will prevent motor malfunction when the input terminal is suspended. No Stalling: Built in overheat protection circuit (TSD) with hysteresis effect, getting you rid of worrying motor stall. Practical Use: Compact in size and light in weight, the installation makes it ideal for DIY and application on vehicle. Specification: Item Type: Step Motor Driver Module Power Supply Voltage: 2V-10V; Signal Terminal Input Voltage: 1.8-7V; 1 Way Working Current: 2.5A; Low Standby Current: Less than 0.1uA; Product Size: Approx. 31 x 32 x 5mm / 1.22 x 1.26 x 0.2in (L x W x H) Mounting Hole Diameter: Approx. 2mm / 0.08in Package List:1 x Step Motor Driver2 x Cable Note:1. Reverse connection of the positive and negative poles of the power supply will definitely cause damage to the circuit.2. When the output is short circuited to the ground or the output terminal is short circuited, and the motor is stalled, the chip will be thermally protected, but it will also cause the chip to burn when the voltage is close to or exceeds 10V and the peak current exceeds 2.5A.
