USB Wi-Fi Drivers

For RT3xxx/RT5xxx Wi-Fi Chips

Embedded SoCs are abundant today and vary in shape, size, functionality and power. When faced with the challenge of setting up a product proof of concept, engineers often tend to work on SoC starter kits or evaluation boards.

What happens when the product requires Wi-Fi connectivity which is missing from the starter kit?

You probably guessed right… Adding a specialised USB Wi-Fi dongle will do the trick.

MCCI has implemented matching USB drivers for USB Wi-Fi dongles based on MediaTek/Ralink RT3xxx and RT5xxx chipsets to make the experience of adding Wi-Fi Connectivity to an embedded system as off the shelf as possible.

By using MCCI’s drivers, you can take advantage of inexpensive, pre-certified Wi-Fi adapters, to add Wi-Fi capability to your product without requiring additional regulatory certifications.

Target customers:

  • Proof of Concept Projects
  • Internet of Things (IoT) products
