Working with Raspberry Pi is always fun, but can often present new challenges when it comes time to expand the functionality and capabilities of a project. In such times, however, it’s always great to find modules like this Serial Expansion HAT for Raspberry Pi, which features an I2C interface with a 2-channel UART, as well as 8 programmable GPIO pins – to let you expand your project in a multitude of different ways.

In terms of functionality, the Raspberry Pi Expander HAT is designed to add more slots for all of the things that you really want to add to your project – but just don’t have the space for. And in addition to offering 8 programmable GPIO pins that you can do almost anything you want to with, this HAT also doubles the UART capabilities with a 2-channel UART via the I2C interface, which is fantastic when compared to the standard single channel UART typically featured on Raspberry Pi Boards.

And finally, just in case you weren’t entirely satisfied with the expansion capabilities that it already offers, these Modular HATs can also be stacked up to 16 times, with each HAT featuring its own I2C address, resulting in up to 32 channels of UART and a ridiculous 128 GPIO pins – more than you could ever need for a single Raspberry Pi project.

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.
