I plan to start with a little experiment and try to make one single motor run in both directions. and I power the H-Bridge with a 6v (4x1,5v) battery. In this one, the ENA and ENB are double pins with jumpers, as you can see in the photo.Īlso, I suppose I don't have to connect any 5v or GRN from the Arduino board since the description of the bridge states: 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. In other models, I notice that the ENA and ENB are pins that you connect to the Arduino board so that you can enable/disable the motors via programming.
I searched for documentation on the web, but didn't find any yet of this specific model.
I notice that there are different variants of the L-298N H-bridge.
