Product Instruction
The MK07 nRF52833 module is a strong, highly adaptable, ultra-low-power Bluetooth mesh module supporting Bluetooth 5.1, based on Nordic® Semiconductor nRF52833 SoC solution, which has a 32 bit Arm® Cortex™-M4 CPU with the floating-point unit running at 64 MHz.
The MK07 nRF52833 modules lead out all I/O resources and power pins. The MK07 series modules have industry-leading functions of full-speed USB, high-speed SPI, NFC-A, and +8dBm output power. The combination of higher output power and Bluetooth 5 technology’s long-range (Long Range) function ensures that the MK07 nRF52832 module becomes a powerful connection and a perfect choice for smart home applications with comprehensive building coverage. The MK07 can be customized and designed to support high-temperature performance up to 105°C, making it an ideal choice for professional lighting and other industrial applications.
The MK07 Bluetooth mesh module brings out all nRF52833 hardware features and capabilities including USB access, up to +8 dBm transmit power up to 5.5V supply considerations, and NFC tag (type 2 / 4) implementation. Complete regulatory certifications enable faster time to market, and reduced development risk completes MOKO SMART’s simplification of your next Bluetooth design!
MK07 series Bluetooth mesh module has two different models — MK07A and MK07B.


MK07A
MK07A integrates a high-performance PCB antenna.

MK07B
MK07B uses a u.FL connector and requires an external antenna.
