* GitHub : https://github.com/rdiot/rdiot-b005.git

* Specs

Description:

Using L298N as the control chip,the module has such characteristics as strong driving ability,low calorific value and strong anti-interference ability. This module can use built-in 78M05 for electric work via a driving power supply part. But to avoid the damage of the voltage stabilizing chip, please use an external 5V logic supply when using more than 12V driving voltage. Using large capacity filter capacitor, this module can follow current to protect diodes,and improve the reliability.

Feature:

L298N Double H Bridge Motor Driver Module Control chip: L298N Logical voltage: 5V Drive voltage: 5V - 35V Logical current: 0mA - 36mA Drive current: 2A(MAX single bridge) Storage temperature: -20°C to +135°C Max power: 25W Size: 43 x 43 x 27mm
