Product Instruction

MK01 series is a powerful, highly flexible, ultra low power tiny Bluetooth® 5 modules 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 smallest Bluetooth module has an ultra-small size of 10mm x 10mm with 28 LGA (Land Grid Array) 0.4mm x 0.4mm pad pins providing 22 GPIOs (including 32.768 kHz crystal and reset pins) of nRF52832CIAA (WLCSP package).

MK01 series Bluetooth module has two different models — MK01A & MK01B.
