I am working with a Sainsmart Uno with SVG header pins. This header is really convenient for hooking a servo to directly, so I have two servos connected to it on D9 and D10 and a 9v battery supplying power via the power jack.
Everything seems to work fine at first, but eventually (sometimes quickly), the board becomes unresponsive. If, instead, I wire my servos to use the 5v pin on the Arduino (not from this SVG header), I don't run into this trouble.
Does anyone know if I am running into a limitation of this header Voltage pin? Has anyone had any success using this mechanism to drive servos? Certainly, I don't NEED to do it this way, but it sure is convenient.
