Zio 16 Servo Controller (Qwiic)

With the Zio 16-Channel 12 bit PWM controller, using the PCA9685 from NXP Semiconductors, you can control up to 16 servos or other PWM-controllable components using I2C.

Each output can be off or on (no PWM control), or set any channel to its own PWM frequency and duty cycle. The PCA9685 operates with a supply voltage range of 2.3v to 5.5v and both the inputs and outputs are 5.5v tolerant. Servos can be connected directly to output pins (up to 25 mA, 5.5v) or controlled with external drivers for more power-hungry applications.

The board comes equipped with two Qwiic connectors to enable easy daisy-chaining. Need even more channels to control something like a hexapod robot? Quickly and easily connect another servo controller with the additional Qwiic connector and 6 solder-jumper configurable address bits. That means you can have up to 62 of these boards operating on the same I2C bus. You can also configure the boards to recognize group addresses, so that multiple boards can be controlled in parallel with a single command.

The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.

Zio 16 Servo Controller (Qwiic) Product Help and Resources

Core Skill: Robotics

This skill concerns mechanical and robotics knowledge. You may need to know how mechanical parts interact, how motors work, or how to use motor drivers and controllers.

3 Robotics

Skill Level: Competent - You may need an understanding of servo motors and how to drive them. Additionally, you may need some fundamental understanding of motor controllers.
See all skill levels

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

2 Programming

Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Great Product

I purchased this module for my newest robotic project and everything went smooth, from the easy connection using the standard 4 pin connector till the ready-to-use code examples. Hope to see more Qwiic modules like this!

This product was very easy to use, particularly for precision control for home projects. I used it for a homemade syringe pump system and it worked perfectly!
