Although the old Jurassic Park, Alien and other mechatronics-based movies of the past made it look easy, many of us Electronics Makers will know that driving a motor is no simple task, and requires a lot of careful planning and forethought to ensure that all of the motors have the necessary power, resolution and other capabilities to behave perfectly – without jittering or grinding to a halt unexpected.

This is why we know you’ll certainly be able to appreciate the addition of this Servo Driver HAT for Raspberry Pi to our catalogue, which features 16 Channels at 12-bit resolution with PWM capabilities and an I2C interface, to help you wrangle those servo motors and bring your project to life – with smooth and seamless motion, as well as perfect accuracy for whatever tasks you need them to handle.

This servo driver HAT, despite offering an incredible amount of extra functionality for Raspberry Pi projects, is designed to be as easy to use as possible, with a simple 2 pin I2C interface for controlling all of the motors in serial. This means you don’t even have to keep a whole bunch of pins spare if you’re planning on using this HAT, and you can simply reserve two pins for all of your servo motor applications – even offering the possibility to power them separately from the Raspberry Pi Boards so as to eliminate any potential problems with power supply to the motors.

Typical Applications for the 16 Channel 12-bit Servo Driver Pi HAT:

The Servo Driver HAT for Raspberry Pi, with 16 Channels of 12-bit resolution output, is the ideal expansion module for when you need to drive a lot of Servo Motors effectively, and without any strange or jittery movements that would otherwise reduce accuracy and effectiveness. Great examples of projects that need this kind of capabilities include robotics like the infamous HexaPod walker, which of course needs two motors per leg (totalling 16 servo motors) in order to actually emulate the creepy and crawly walking style of spiders and other 8-legged arachnids.

However, even though these Pi HATs are amazing for these types of applications, they are not necessarily confined to just Robotics projects, and could just as easily be used for unique arcade games, stock systems in small stores, or for any number of other projects yet to be dreamed into existence. So get out there and start thinking of how you would like to use up to 16 servo motors, simultaneously or individually, to create a unique project that

When it comes to producing unique electronics components and modules, there are very few brands that can provide the quality that Waveshare can. Based in the Futian District in Shenzhen, China, Waveshare are experts in developing electronics to a high standard of quality, which have been thoroughly tested to work seamlessly with corresponding development platforms and systems – such as the E-Ink HATs for Raspberry Pi’s.

What we love most about Waveshare is how they are dedicated to providing quality products, and have moved away from the typical “Made in China” stigma – cheap products with cheap parts and components. Instead, Waveshare understand the value of supplying quality products and building sustainable relationships with international resellers and distributors. They know that consistent quality will result in consistent business, and as such they always ensure strict quality control for each and every product that comes out of the manufacturing plant.

We are always excited to peruse through their vast catalogue of exciting new products to find unique modules, components or even entire development boards that are designed with quality in mind. Because we know that every cent that we spend with Waveshare will be well-spent, with each product that order adding real value to our own catalogue of products.
