1 Device Overview
1.1 Description
RF-BM-4044B2 module is designed based on CC2640R2FRSM Bluetooth Smart BT 5.0 System-on-Chip, fully supports
the single mode Bluetooth Low Energy operation. The module contains a 32-bit ARM Cortex
TM
-M3 processor, with the
working frequency at 48.0 MHz which is the same as the main processor. The module has rich peripherals function
libraries, and a unique ultra-low power sensor controller, which is fit for connecting the external sensors in the sleep
mode and/or acquiring analog and digital data independently.
