Feature:1. Double H-bridge design can drive two DC motors at the same time, single-channel 7A current2. Low heat generation, no heat sink, small size and low power consumption, very suitable for battery power supply3. Signal optocoupler isolation input, which can be directly controlled by IO port without interference4. Under-voltage protection to prevent instantaneous high current from burning down the module5. Highpower TVS and electrostatic discharge circuit, suppress transient interference pulse and static electricity, stable and reliable products, industrialgrade designSpecification:Item Type: DC Motor Driver ModuleSupply Voltage: 6.5V-27VRated Output Current: 7APeak Current: 50AControl Signal Voltage: 3-6.5VPWM Frequency Range: 0-10kHzPWM Minimum Pulse Width: 10usWorking Temperature: -25-80Length: Approx. 55mm or 2.1inWidth: Approx. 55mm or 2.1inHeight: Approx. 16mm or 0.6inMounting Hole Diameter: Approx. 3mm or 0.1in.Package List:1 x Drive ModuleNote:The power supply voltage is 6.5Vand 8209 27V.
