Support voltage 6.5V-27V, with undervoltage protection and power supply transient interference suppression. Dual motor interface, each with a rated output current of 7A. Features control logic similar to L298, supporting three-wire control for enable, reverse, and brake functions. Enable signal can be externally connected to PWM; forward and reverse control signals can be connected in series with limit switches. Control signals use current drive mode, compatible with most microcontrollers for direct drive. All control signals are optically isolated. Includes electrostatic discharge protection circuitry. Power supply voltage range: DC 6.5V-27V Rated input voltage: DC 12V/24V Number of output channels: 2 Rated output current per channel: 7A Peak current per channel: 50A Maximum compatible motor: 12V-40W, 24V-120W Control signal voltage range: 3V-6.5V Control signal current per channel: 3-11mA Supported PWM range: 0-100% Supported PWM frequency range: 0-10kHz Operating temperature: -25C to 80C Color: As shown Material: PC Package Contents: 1 x Motor Drive Board (Note: Due to different product batches, appearance may vary slightly, but this does not affect functionality) Other items not included.
