Product Instruction

The MK13 series is a highly flexible and powerful Bluetooth® 5.2 module that is based on the Nordic® Semiconductor nRF5340. It is the world’s first wireless SOC that comes with two Arm® Cortex®-M33 processors.

The module combines two flexible processors, an operating temperature with a ceiling of 105 °C, and an advanced set of features. These aspects make it the ideal choice for professional lighting, LE audio and advanced wearable, among other IoT applications.


MK13A integrates a high-performance PCB antenna.


MK13B uses a u.FL connector and requires an external antenna.
