Product Instruction
The MK02 series nRF52832 module is a BLE 5 module boasting NFC function, giving it the easy possibility of becoming highly integrated, using the high-performance Nordic nRF52832 SoC solution. The MK02 Bluetooth module works with a wide variety of protocols, with complete protocol concurrency, including high-speed 2 Mbps. Additionally, Bluetooth mesh can run concurrently with Bluetooth LE, enabling smartphones to configure and control mesh nodes. It was designed to handle a high data rate with short-range wireless communication in the 2.4GHz ISM band. MK02 has a 32 bit ARM Cortex-M4 CPU, flash memory and analogue and digital peripherals. The MK02 provides low power, ultra-low-cost BLE and proprietary protocols for wireless transmission applications.
The MK02 nRF52832 module extracts the rich I/O resources. Through an immersion gold half-hole process, which is convenient for users to develop more applications. The module provides two high-performance solutions using its antennas. MOKO engineers provide rich selections and precise recommendations according to customers’ application scenarios and product designs. MK02 can be fitted with a Concurrent master (slave) firmware with full AT commands to facilitate users to rapidly initiate function verification. MOKOsmart has many years of valuable, effective design experience and can provide reliable support in Bluetooth software and hardware development.
MK02 series Bluetooth NFC module has two different models — MK02D and MK02E


MK02D
MK02D integrates a high-performance PCB antenna

MK02E
MK02E uses a u.FL connector and requires an external antenna.
