1. Product Instruction
MK07 series is a powerful, highly flexible, ultra low power Bluetooth® 5.1 module based on world-
leading Nordic® Semiconductor nRF52833 SoC solution, which has a 32bit Arm® Cortex™-M4 CPU
with floating point unit running at 64MHz. MK07 series is capable of the latest and greatest features
of Bluetooth® 5.1, the most prominent being Direction Finding1, taking Bluetooth positioning to
new heights.
MK07 series brings out all nRF52833 hardware features and capabilities including USB access, up to
+8 dBm transmit power up to 5.5V supply considerations, . Complete regulatory certifications
enable faster time to market and reduced development risk completes MOKO SMART’s
simplification of your next Bluetooth design!
MK07 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. Bluetooth
mesh, 802.15.4, Thread, Zigbee, proprietary 2.4 GHz protocols supported.
1.1 Model Classification
There are two models of MK07 series Bluetooth module — MK07A and MK07B. The two models
both have a small size of 21 x 13.8 x 2.3mm with all 40 GPIOs of nRF52833QIAA (7x7mm aQFNTM73
package).
The difference between MK07A and MK07B is the antenna design.
MK07A integrates a high-performance PCB antenna.
MK07B 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.
