Feature: 1. Double H-bridge design can drive two DC motors at the same time, single-channel 7A current 2. Low heat generation, no heat sink, small size and low power consumption, very suitable for battery power supply 3. Signal optocoupler isolation input, which can be directly controlled by IO port without interference 4. Under-voltage protection to prevent instantaneous high current from burning down the module 5. High‑power TVS and electrostatic discharge circuit, suppress transient interference pulse and static electricity, stable and reliable products, industrial‑grade design Specification: Item Type: DC Motor Driver Module Supply Voltage: 6.5V-27V Rated Output Current: 7A Peak Current: 50A Control Signal Voltage: 3-6.5V PWM Frequency Range: 0-10kHz PWM Minimum Pulse Width: 10us Working Temperature: -25℃-80℃ Length: Approx. 55mm / 2.1in Width: Approx. 55mm / 2.1in Height: Approx. 16mm / 0.6in Mounting Hole Diameter: Approx. 3mm / 0.1in. Package List: 1 x Drive Module Note: The power supply voltage is 6.5V‑27V. The power supply must not be connected reversely or exceed 27V, otherwise the module may be burned out. Recommended to connect a 15A fuse in series with the power input terminal
