The easiest way to hook the servo breakout up to your Pi is using a breadboard and connecting it to the Pi using I2C:
- Pi 3V3 to breakout VCC
- Pi GND to breakout GND
- Pi SCL to breakout SCL
- Pi SDA to breakout SDA
- Servo orange wire to breakout PWM on channel 0
- Servo red wire to breakout V+ on channel 0
- Servo brown wire to breakout Gnd on channel 0
Check your servo's datasheet to verify which wires go to which pin!
In the example image above with a single servo motor, we are powering the motor from an external 5V power supply connected to the terminal block on the breakout board via a DC power adapter. Make sure you connect the wires correctly, with +/+ and GND/GND.
