Product Instruction
The MK05 series nRF52810 module is a Low-end Bluetooth Module launched by MOKO, using Nordic nRF52810 SoC solution.
The MK05 nRF52810 Bluetooth 5.0 module has multiprotocol capabilities with full protocol concurrency. It supports BLE® (Bluetooth Low Energy) and a 2 Mbps bitrate of Bluetooth 5, providing increased application throughput and up to 50% energy savings. It supports channel selection algorithm #2 (CSA #2), which enhances its ability to coexist with other Bluetooth LE devices.
The MK05 series Bluetooth nRF52810 module is a Low-end Bluetooth Module launched by MOKO. The MK05 series has the same size and package design as the MK02 series, for easy implementation in nRF52832 and nRF52810. This does not modify the fast switching of PCBA design. MK05 has a very high-cost performance. With the pre-burned MOKO AT command firmware, MK05 can quickly be used as the Role of Peripheral + Broadcaster to realize the IoT application of customers’ Bluetooth transparent transmission.
MK05 series Bluetooth 5.0 module has two different models — MK05A and MK05B.


MK05A
MK05A integrates a high-performance PCB antenna

MK05B
MK05B uses a u.FL connector and requires an external antenna
