1. Product Instruction
MK11A is a low-cost and low-power consumption Bluetooth® module based on Texas Instruments
CC2642R SoC solution, which has a powerful 48-MHz Arm® Cortex™-M4F processor supporting
Bluetooth® 5.1 Low Energy and Proprietary 2.4 GHz applications.
The system CPU is the foundation of a high-performance, low-cost platform that meets the system
requirements of minimal memory implementation, and low-power consumption, while delivering
outstanding computational performance and exceptional system response to interrupts.
MK11A has a size of 25mm x 17mm x 2.8mm with 36 pins providing 30 GPIOs and integrates a high-
performance PCB trace antenna.
