Integration Tips for Arduino and Raspberry Pi 🧠

• Drive with standard PWM control signals (typ. 50 Hz) from an Arduino or Raspberry Pi via a suitable GPIO/PWM pin or a servo driver module (e.g., PCA9685).
• Use a dedicated, regulated external 5 V supply for the servo; connect grounds in common with your microcontroller to ensure signal reference integrity.
• Avoid powering the servo directly from a board’s 5 V pin if current draw could exceed the regulator’s capacity.
• For Arduino, the built-in Servo library offers quick setup; on Raspberry Pi, use libraries that provide clean PWM (hardware PWM or a servo driver).

Whether you are prototyping on Arduino, building a Raspberry Pi-controlled robot, or integrating precise motion into compact mechanisms, the SG90 RC Mini Servo is a proven, affordable choice for dependable motion control in your next project. 🛠️
