Arduino Shield SIM808 GSM/GPRS with GPS

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.
