The SMD BLE module contains the TI CC2541 chip. It is low cost and has very low power consumption. It is small and simple to use. It supports BLE communication with Android.
The CC2541 supports the Bluetooth 4.0 protocol with low power consumption and it is very convenient to use as a male header type pin output by making the pins suitable for breadboard use for convenient use. The card has TI "IN CC2541 Bluetooth 4.0 chip. The working voltage is 5V and RX, TX, AT and RESET pins are pulled onto the card for maximum comfort.
The bluetooth module, which you can easily use with Arduino or different microcontrollers, can be used with any bluetooth transmitter, computer or Android devices. With standard pin structure, you can easily control it in desired environment and communicate with Android.
Supporting Bluetooth 4.0, this card allows communications at a frequency of 2.4GHz and has a communication distance of about 30 meters in the open area, which can be used in many hobby, robotics and academic projects.
