Single DC Motor Drive 8-35V 30A Full PWM High Power H Bridge Forward Reverse
1, optical isolation The input end uses Sharp 10MB high-speed optical auxiliary isolation to achieve superior anti-interference ability 2, the input terminal large capacitance filter The input end uses 1000uF/35V large capacity, long life, low ESR filter capacitor to ensure module power supply stability. 3, external DC output Preset two sets of external power supply interfaces, which can realize on-board DC-DC external power supply and support +5V/0.5A output. 4, status indication function Five high-brightness LEDs onboard, indicating power input, operating state and direction of the motor 5, full bridge driver chip The full-bridge driver chip is used as the main control chip, and the performance is super-half-bridge drive scheme. 6, enhanced heat dissipation design Self-contained heat sink for enhanced digital heat protection to ensure heat dissipation during high current applications 7, low internal resistance MOS Adopt high current and low internal resistance MOS tube, inner Yang as low as 4 milliohms 8, the control logic is simple Only three control signals INA, INB and PWM signals greatly simplify the control method
Module interface definition
1, VIN & GND: power input, connected to the power supply 2, M+&M-: DC motor interface, connected to DC motor 3, +5V & GND: external power supply interface, maximum output 5V/0.5A 4, VDD: optocoupler power supply terminal, 3.3V or 5V 5, INA, INB: control termination, single chip or PLC 6, PWM: speed signal input Note: The power input terminal (VIN&GND) has no anti-reverse protection. Before powering on, be sure to check if the wiring is wrong and prevent the module from burning!
