Data Sheet

1. Product Instruction

MK01 is a powerful, highly flexible, ultra low power Bluetooth

5 module based on

Nordic

Semiconductor nRF52832 SoC solution, which has a 32 bit Arm

Cortex™-

M4 CPU with floating point unit running at 64 MHz.

MK01 module is multiprotocol capable with full protocol concurrency. It supports

BLE

(Bluetooth Low Energy), including the high-speed 2 Mbps feature. Bluetooth

mesh can be run concurrently with Bluetooth LE, enabling smartphones to provision,

commission, configure and control mesh nodes. NFC, ANT and 2.4 GHz proprietary

protocols are also supported.

MK01 has a ultra-small size of 10mm x 10mm with 36 LGA (Land Grid Array) 0.4mm

x 0.4mm pads providing 22 GPIOs (including 32.768 kHz crystal and reset pins) of

nRF52832CIAA (WLCSP package).

1.1 Model Classification

MK01 Bluetooth module has two different models -- MK01A & MK01B. The

diffenence between MK01A and MK01B is the antenna design.

MK01 integrates a high-performance ceramic chip antenna

. BLE advertising

distance can reach more than 80 meters.

MK01 uses a u.FL connector

and requires an external 2.4Ghz antenna. BLE

advertising distance can reach more than 150 meters using 2.4GHz 3dBi Terminal

Mount Dipole Antenna
