Features: Uses L298N as the main drive chip, it has strong driving capability, low heat generation, and strong anti-interference ability. Built-in 78M05, it gets power from the drive power, but when the drive power is over 12V, use the external 5V power supply as the power supply. Large capacity filter capacitor, backflow protection diode, more stable and reliable. Specification: Material: Fiberglass board, electronic component Size: 4.3 x 4.3 x 2.7 cm / 1.69 x 1.69 x 1.06 inches Color: As the picture shows Quantity: 1 pc Product parameters: Module: Dual H-bridge motor control module Working mode: H-bridge drive (dual path) Main control chip: L298N Logic voltage: 5V Drive voltage: 5V-35V Logic current: 0mA-36mA Drive current: 2A (MAX single bridge) Storage temperature: -20 to +135 /-4 - 275 Maximum power: 25W Precautions: 1. When your drive voltage (12V is input, meaning the input range is 7 to 12V), it can supply to the onboard logic with a 5V power supply; when using the onboard after 5V power supply, the +5v interface. The power supply does not input voltage, but can provide 5V voltage for external use. 2. When the drive voltage is higher than 12V, but less than or equal to 24V (the chip manual suggests supporting 35V, but it is very good that the maximum voltage of 298 conservative applications supports up to 24V according to experience) for example, the motor with a rated voltage of 18V needs to be driven. First, remove the jumper on the 5V output board. Then, 5V is reached outside the 5V output port. 5V enables the current to be a control signal with a level of 5V. When the signaling input is valid and the power supply is normal in the motor control module, the motor control module outputs the current. Otherwise, even if the power supply is normal, there is no current on the motor. Voltage to the L298N internal logic circuit power supply. (this is a high-pressure, unconventional application) Note: No retail packaging. Please allow 0-1 cm error due to manual measurement. Make sure you don't mind before bidding. Due to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you Package includes: 1 x L298N driver module
