RAK4631 Can't trigger a Servo

WisBlock

Hey guys,

I’ve been trying to get a servor running with me RAK4631 using the RX0 Pin on the Base, how ever I somehow don’t seem to be able to trigger any Motion.

I was trying it with "myservo.attach(PIN_SERIAL1_RX); " but that doesn’t seem to do the trick. Any ideas what I’m doing wrong?

Welcome to the forum @Att1B3ar

Did you connect the servo directly to RX0 pin? That will not work. The max output current of a nRF52 GPIO is ~15mA.

You need an external circuit between the GPIO and the servo motor or use one of our motor driver modules WisBlock Motor.
