URUAV DIY 4DOF Robot Arm 4 Axis Acrylic Rotating Mechanical Robot Arm With R3 4PCS Servo
39,66€ 54,42€

Q: I assembled the robot arm. But if I connect the included powersupply (5.16V) the voltage drops to 3.21V. Anybody any idea what to do. FYI if I connect the USB cable the voltage is 5.0 exactly and the system is running perfectly. But I need a solution with the included power supply.

edude Sounds like something is wrong with powersupply or it's connection. It could be there is shorting on the connector, or powersupply is not able to provide the enough current. What is the voltage of power supply when not connected?

Really great device. Enough freedom to put your material in the correct position. Delivery time was super 2.5 weeks.
