RF-BM-4044B2 module is designed based on CC2640R2FRSM Bluetooth Smart BT 5.0 System-on-Chip and fully supports the single-mode Bluetooth Low Energy operation. The CC2640R2F 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. RF-BM-4044B2 is pin-compatible with the RF-BM-4044B3 in SMT package.
