HC-09 Bluetooth CC2541 Serial Port Module 4.0 BLE

The HC-09 Bluetooth Module development board has a serial connection, one of the simplest and most practical modules in the market, which is used to convert the serial port to Bluetooth, in other words, by using this module, we can establish virtual serial communication (wirelessly) between Create two devices or MCU.

Note: note that this module is not suitable for sending files.

Using the BLE4.0 Bluetooth version 4 module with the CC2541 chip provides the excellent performance of a leading RF transceiver with an advanced industry-standard MCU 8051, in-system programmable flash memory, 8KB RAM, and many other powerful features and peripherals. combines CC2541 is very suitable for systems with very low power consumption, the main reason for the low power consumption of this module is the high speed of data transfer in the shortest time.

Other features of this module include transparent data transmission, communication distance up to 60 meters, the possibility of setting a password, the ability to support Android and iOS operating systems, and the BELETOOL application.
