Product Instruction

MK06 nRF52811 module is a multiprotocol lower-end Bluetooth 5.1 SoC solution capable of Bluetooth Direction Finding and Bluetooth Long Range, 802.15.4, Thread and Zigbee.

MK06 nRF52811 module supports a wide range of wireless protocols. It supports BLE® (Bluetooth Low Energy), and is capable of Bluetooth® Direction Finding, as well as Long Range and 2 Mbps. ANT, Zigbee, Thread and 2.4 GHz proprietary protocols are also supported.

For simple applications that require Bluetooth Direction Finding or Long Range, MK06 Bluetooth 5.1 Module is the absolute best choice. MK06 provides two kinds of antenna designs, which is more conducive to the selection of user diversity and works very well for the development of real-time positioning (RTLS) solutions. MK06 can burn AT command firmware with simple functions, enabling quick and easy operation.

MK06 series Bluetooth 5.1 module has two different models — MK06A and MK06B.
