RF2541-PL2 : BLE 4.0 UART BLE Module With OTA Capability

RF2541-PL2 is a BLE module and adopts CC2541 SOC chip from TI, RF2541-PL2 communicate with others through UART interface, with all the feature of BLE 4.0, it is easy to use, the features include: low power consumption, long distance, and strong anti-interference ability. There are two modules which constructs the master and slave function: RF2541- PL2 master and RF2541- PL2 slave. Those two modules come with same hardware but different software inside.
