![]() ![]() The board can be supplied with powerĮither from the DC power jack (7 - 12V), the USB connector (5V), or the VIN pin of the board (7-12V). Or, if supplying voltage via the power jack, access it through this pin.ĥV - This pin outputs a regulated 5V from the regulator on the board. Volts from the USB connection or other regulated power source). But from Arduino Uno Rev3 Faq, Vin - The input voltage to the Arduino board when it's using an external power source (as opposed to 5 Here are 3 of the schematics I've found online, Since I am planning to use the 5v screw terminal as output I am choosing to leave the 5v jumper on. I am connecting 7.5v to the Vin and Gnd to the motor driver controller screw terminal, and I wish the power the Arduino from the 5v screw terminal. Different online schematics about how to connect them are mostly similar - but they differ in powering the Arduino from the drive controller's 5v pin. ![]() I am trying to setup L298N motor driver controller with my Arduino. ![]()
