When taking a broad overview at Electronics and the many different microcontrollers available, it’s hard to ignore just how capable, functional and relatively easy Raspberry Pi is, with excellent foundations and contributors throughout the world all working towards making Raspberry Pi even more accessible and useful in various different industries. This is why we’re always quite excited to get new Raspberry Pi HATs in, as Pi HATs typically open up fresh new possibilities and opportunities to take advantage of, with this 2-Channel Isolated CAN Expansion HAT from Waveshare being a prime example of just that.

This clever CAN expansion HAT has been designed to help Makers integrate the CAN protocol into various different projects, and while the CAN protocol was initially designed for complex systems that didn’t have a microcontroller to process and keep track of everything, such as vehicles in the automotive industry, it has recently been gaining in popularity in the hobbyist and Maker scene too. This means that Makers can now utilise cost-effective MCU’s like Raspberry Pi Boards to communicate with and control large complex systems, while the HAT functionality means that it is relatively easy to use, as well as relatively easy to integrate.

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.
