CC2541 Bluetooth 4.0 Transmission Module for Arduino / Raspberry Pi
This is a type of low energy data transmission Bluetooth module based on CC2541 and it follows the Bluetooth specification BLE V4.0. Combining the advantages of compact size£¬ extra low power consumption£¬ strong anti-interference and long communication distance£¬ it is very suitable for short range wireless communication in Things of Internet. The module integrates PCB antenna on board. It can be used to communicate with other Bluetooth devices such as iPhone system. Through AT commands£¬ the user can modify the baud rate£¬ device name£¬ passkey and other parameters. Features: Bluetooth protocol: Bluetooth Specification V4.0 BLE£¬ send and receive no byte limit£¬ with IPHONE 4S long distance communication can be 110 meters under the open environment. Operating Frequency: 2.4GHz ISM band Modulation: GFSK (Gaussian Frequency Shift Keying) Sensitivity: -84dBm at 0.1% BER Transfer rate: Asynchronous: 6 Kbps Synchronous: 6 Kbps Security Features: Authentication and encryption Support Services: Central & Peripheral UUID FFE0£¬ FFE1 Power consumption: automatic sleep mode£¬ standby current 400uA ~ 1.5mA£¬ transmission 8.5mA.
