RF-Star CC2640R2F BLE5.0 Module RF-BM-4044B2 2.4 GHz Wireless Transceiver for HVAC
RF-BM-4044B2 and RF-BM-4044B3 modules are designed based on CC2640R2FRSM System-on-Chip, which fully supports the single-mode Bluetooth 5.1 Low Energy operation. The module contains a 32-bit ARM Cortex-M3 processor with a working frequency of 48.0 MHz.

The module has rich peripheral function libraries and a unique ultra-low power sensor controller, which is fit for connecting the external sensors in sleep mode or independently acquiring analog and digital data. RF-BM-4044B2 is pin-compatible with RF-BM-4044B3. 4044B2 is the high-performance onboard PCB antenna, and the 4044B3 is equipped with an IPEX connector for the feasible external antennas.
