Arduino 16-channel PWM-Servo Shield PCA9685

Product detailed description

Do you want your cool robot, spider or any of your creations to have moving parts? Or maybe you want to drive a lot of LEDs with precise PWM output? And suddenly you realize that your microprocessor has a limited number of PWM outputs! What now? Use only two pins to control 16 PWM outputs! You can even daisy-chain up to 62 boards and control up to 992 PWM outputs. It is 5V compatible, which means you can control it from a 3.3 microcontroller and still safely drive up to 6V outputs. Terminal block for power supply (or you can use the pins on the side). 3 pin connectors in groups of 4 so you can connect 16 servos at once. You can add a large capacitor on the power supply (in case you need it). 330 Ω series resistors on all output lines to protect them, and also for the LEDs.

Almost all servos are designed for 5-6V operation. Keep in mind that many servos moving simultaneously (especially large powerful ones) will need a lot of current. Even a micro servo will draw several hundred mA when moving. Some high torque servos will remove more than 1A under load.

Remark:

• This product is not a standalone functional unit and may require professional installation.
• Product images are for illustration purposes only and may sometimes differ from the actual appearance of the item. However, this does not change its basic properties.
• After mounting the shield, please check that the pins from the bottom side do not touch the component housings on the bottom plate! This could cause a short circuit and destroy the shield or even the motherboard. Goods damaged in this way are not covered by the warranty!
