rf-star rf-bm-4044b3 ipex antenna cc2640 bluetooth module bt5.0 module

 

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-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 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. rf-bm-4044b2 is pin-compatible with the rf-bm-4044b3 in smt package.
