Is a Wireless MCU Right for Your Project?


Benefits of Wireless Microcontrollers

Designing and building wireless products is complicated. Choosing a microcontroller with wireless functionality can reduce the difficulty in IoT design, helping you get to market faster with lower production costs.

Wireless Microcontrollers (MCUs) - Modules and SoCs

All-in-One Solution

If your project requires flexible connectivity, then a wireless microcontroller might be a good choice. Wireless MCUs offer multiple functions (including connectivity) in a single chip. In general, decreasing the number of chips (MCU or otherwise) in a design reduces the design difficulty and cost. The primary reason is that the manufacturer is doing some of the work for you. With the right wireless MCU, all you need to do is to power the device on and connect it.

No RF Expertise Needed

To further simplify the design process, consider a wireless MCU module. Though a wireless microcontroller IC can connect via Wi-Fi, Bluetooth or other technology, it needs an antenna to broadcast that connection. On its own, building an antenna that performs well is a challenge. Add-in the certifications required and designing your own antenna becomes even more difficult and costly.

Wireless MCU modules remove the RF obstacles associated with IoT design. Our modules require no RF expertise because they include antennas built for optimal RF performance. We further simplify the RF process by getting our modules pre-certified in many countries so that you can bypass the certification process and focus on your product.

All-in-One Support

To further accelerate your development, our easy-to-use integrated development environment and MPLAB® Harmony embedded software development framework allows you to work directly with the wireless stack. Rapid prototyping is a reality when you can use one tool to program your application including wireless connectivity. Learn more about MPLAB Harmony.
