long range smallest ti cc2640r2f rf-bm-4044b4 ble4.2/bt5.0 micro bluetooth module
rf-bm-4044b4 -2 module is designed based on cc2640r2frsm bluetooth smart ble4.2 or bt 5.0 system-on-chip, fully supports the single mode bluetooth low energy operation. the module contains a 32-bit arm cortextm-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.
as a member of bt-sig, texas instruments (ti) introduced cc2640 series of soc low-power bluetooth transceiver. with arm ® cortex ® -m3 inside, its most prominent features are rich periphery(including 31 ios, uart, spi, pwm, adc, analog comparator, op-amp), super wide working voltage (1.8v – 3.8v), extreme low energy consumption (<0.1μa).
modules, working as a bridge between smart phones and peripherals, make it simple to develop host applications. in the bridge mode (with usart, users’ products, embedded with the modules,can communicate with mobile devices (bluetooth 4.0 supported) with ease. it realizes the super smart control and management.
rf-star is the strategic partner of ti china in the field of wireless.
rf-bm-4044b4-2 uart design for user interface, full-duplex bi-directional communication, and supporting the minimum baud rate of 4800 bps;
rf-bm-4044b4-2 it has 40 channels (channel space at 2mhz), among which there are 3 fixed radio channels and 37 data channels of adaptive automatic frequency hopping.
rf-bm-4044b4-2 it has a wide output power adjustment (-21dbm ~ 5 dbm) and a high gain receiving sensitivity of -97 dbm.
