as a member of bt-sig, texas instruments (ti) introduced cc254x series of soc low-power bluetooth transceiver. with classical 51 kernel inside, its most prominent features are rich periphery (including 21 io, uart, spi, usb2.0, pwm, adc, analog comparator, op-amp), super wide working voltage (2v – 3.6v), extreme low energy consumption (<0.4μa), and very short wake-up delay (4μs)

  • transmit power: 4dbm
  • communication distance: 150m
  • core programme: cc2540
  • bluetooth version: bt 4.0
  • core strengths: extend transmission distance,external antenna

 rf-star bluetooth ble 4.0 ipex antenna cc2540 module transparent transmission module

rf-bm-s02i is a bluetooth low energy (ble) module based on ti cc2540f256, an 8051 core ble system-on-chip (soc). this pcb module integrates a 32 mhz crystal, a 32.768 khz crystal, an lc balun, an rf matching filter, and a meander line ipex connector. it is pre-programmed with the ble 4.0 stack and an application communication protocol over its full speed usb interface. it can be used to design a usb dongle to easily establish ble connection from a device to smart phones. very low-power sleep modes are available. short transition times between operating modes further enable low power consumption. oes not have the usb interface of the rf-bm-s02 and rf-bm-s02i, and provides lower maximum output power in tx mode. the rf-bm-s02a also adds a hw i2c interface.
