1. Product Instruction
MK06 series is a powerful, highly flexible, ultra low power Bluetooth® 5.1 module based on Nordic®
Semiconductor nRF52811 SoC solution, which has a 32bit Arm® Cortex™-M4 CPU with floating point
unit running at 64MHz.
MK06 is capable of the latest and greatest features of Bluetooth® 5.1, the most prominent being
Direction Finding
1
, taking Bluetooth positioning to new heights.
MK06 supports an extensive range of wireless protocols. It supports BLE® (Bluetooth Low Energy) ,
and is capable of Bluetooth® Direction Finding in addition Long Range and 2 Mbps. Thread, and 2.4
GHz proprietary protocols are also supported.
1.1 Model Classification
There are two models of MK06 series Bluetooth module — MK06A and MK06B. The two models
both have a small size of 21 x 13.8 x 2.3mm with all 30 GPIOs of nRF52811QFAA (QFN48 package).
The difference between MK06A and MK06B is the antenna design.
MK06A integrates a high-performance PCB antenna.
MK06B uses a u.FL connector and requires an external 2.4Ghz antenna.
MOKO development team can assist you in selecting high-performance antennas that suit your
needs.
1. Direction Finding enables positioning solutions to not only rely on received signal strength indicator
(RSSI), but also the actual direction of a signal. This improves accuracy significantly and opens new
possibilities for applications in this segment. There are two types of methods for determining direction,
angle of arrival (AoA), where the direction of the received signal is calculated, and angle of departure
(AoD), where the direction of the transmitted signal is calculated.
