Description
HY-254104 Bluetooth low energy UART protocol module is a single mode device targeted for low power sensors and accessories.
HY-254104 offers all Bluetooth low energy features: radio, stack, profiles and application space for customer applications. The module also provides flexible hardware interfaces to connect sensors.
HY-254104 can be powered directly with a standard 3V coin cell batteries or pair of AAA batteries. in lowest power shutdown mode it consumes only 0.5 uA and will wake up in few microseconds.
HY-254104 transmission distance of 50 meter. (At face to face, free space, 1.2 Meter high from Ground for testing).
Bluetooth IC：TTC2541 6*6*0.9mm 40pin IC / use TI CC2541 IC dice
