rf-bm-s01 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 pcb antenna. 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. rf-bm-s01 is pin-compatible with the rf-bm-s01a in smt package, if the usb is not used on the rf-bm-s01 and the i2c/extra i/o is not used on the rf-bm-s01a. compared to the rf-bm-s01, the rf-bm-s01a provides lower rf current consumption.oes not have the usb interface of the rf-bm-s01, and provides lower maximum output power in tx mode. the rf-bm-s01a also adds a hw i2c interface.
