The Servo Expansion Board adds 16 PWM (Pulse Width Modulation) outputs to your Omega. With this expansion, you will be able to get started with your project quickly by connecting standard servos directly to the onboard 3-pin connectors. You can use this little board for anything with moving parts, such as robotics or driving DC motors. You can also make a light show with LEDs by controlling their brightness!
Power the Servo Expansion by plugging it into a dock that will supply 5V to the 16 PWM channels, which should be enough power for a multitude of LEDs or a few servos under a light load. If youâre using more than two servos or a few really powerful one, there is an included DC barrel jack adapter on the expansion board to accept a separate power supply. The PWM signal will be stepped up to the voltage coming in from the barrel jack. The Omega and dockâs 5V line is isolated from the DC barrel jack for protection, so youâll still have to provide power to your Omega.
The Onion Omega boards we carry are separated into three different categories: Mainboard, Dock and Expansion Board. This board falls into the Expansion Board category, meaning you will need an Omega Dock that is equipped with a 30-pin Expansion Header like the Expansion Dock or Arduino Dock R2.
