Features:
Ultra-small size, only 3.5cmx4.3cm (smaller than eggs)
Support voltage 6.8V-26V (not recommended for long time operation above 15V), anti-reverse connection, dual output, maximum continuous current 2.5A per load, independent 3A overcurrent protection for each channel, overcurrent protection action current 2.5- 6A (motor stall current can't exceed 6A), the motor can be recovered after over-current protection, and the drive module will not be burned because the load current is too large.
The optocoupler is fully isolated, and the L298N has the same drive logic. Each channel supports three-wire control enable, forward and reverse, and brake. The enable signal can be connected to external PWM speed regulation. The direction signal can be connected to the limit switch limit.
The control signal uses sink current drive mode to support most 5V MCU direct drive
The control signal interface can be connected using the commonly used 2.54mm pitch 10P crimping head, the female or the DuPont line.
Easy to use and secure with high quality plug-in terminals
Φ3 positioning hole, can be fixed by common M3 screws
Please use 12V for long time operation, do not run for 24V for a long time.
The following figure connects a 2 ohm high-power resistor in series with an ammeter and then connects it to the module output to supply a 7-8V power supply to measure its actual load capacity.
