Notice that the servo motor is driven from the + 5 V pin of the Nucle-F411RE development board (Pin 18, connector CN7). This pin has enough current capacity to drive the SG90 servo motor. In this project the servo motor control pin is connected to GPIO pin PA_8 which is a PWM ...
SG90 is a low-cost and high-output power servo motor. It can rotate up to 180 degrees and each step can be of maximum of 90 degrees. Moreover, it is small enough that it can easily fit into your robotics ARM or obstacle avoidance robotics projects. On top of that, it requires only ...
