As humans, Communication comes naturally to us, as most of us are born with all of the senses and peripherals that we need to effectively pass information to each other – whether through speech, sign language or even simple facial expressions. However, we certainly take this for granted, and this becomes apparent when you try to get two different Electronics Modules or components to communicate with each other, but in different languages. In fact, even though there are a wide range of different Serial Communications protocols, all quite similar in a few ways, even these can’t always communicate effectively without some kind of converter or “Translator” to match the incoming signals with what the output device is expecting.

This is precisely what makes the RS485 to Ethernet Converter such a great tool for anyone who likes to deal with serial communications protocols like RS485 and RJ45, as it allows these two similar but subtly different protocols to effectively communicate, despite the fact that they essentially “speak” different “Dialects”. This enables you to utilise the major benefits of each protocol, but without sacrificing on any functionality, allowing you to communicate with robotics projects via Ethernet, or control multiple RS485 and RJ45 slave devices without having to develop separate systems for each protocol.

In addition to a great quality design, this serial converter module also features a range of great benefits that improve performance and reliability, as well as user convenience and protections against a variety of common and uncommon faults. So let’s take a closer look at some of these awesome features:

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.
