ماژول درایور موتور DC و استپر موتور Bipolar دو کاناله L298N

Description:

This module uses ST's L298N chip as the main drive, with driving ability, low heat, anti-jamming features.
This module can be used to take power through the built-in 78M05 drive power part of the work, but in order to avoid damage to the regulator chip, when a drive voltage greater than 12V, please use an external 5V logic supply.
Two enable inputs are provided to enable or disable the device independently of the input signals.
This module uses high-capacity filter capacitors, freewheeling diode protection, reliability can be improved.
The emitters of the lower transistors of each bridge are connected together, and the corresponding external terminal can be used for the connection of an external sensing resistor. An additional supply input is provided so that the logic works at a lower voltage.

Precautions:

1. When your drive voltage (the figure identified as 12V input, can accept the actual input range is 7-12V ) to 7V-12V, they can enable the onboard 5V logic supply, when using the onboard 5V power supply after, interface + 5V power supply voltage is not input, but can lead to 5V voltage for external use. (This is the routine use!)
2. When the drive voltage higher than 12V, 24V or less (chip can support manual proposes to 35V, but follow through when you experience generally 298 to support a conservative application of the maximum voltage 24V has been very great!), For example, to drive a rated voltage
of 18V motor. First, you must unplug the onboard 5V output to enable jumper caps. And then 5V output port access external 5V voltage L298N internal logic circuitry. (This is a high-voltage driver unconventional application!)
