Bluetooth BLE Module
This module is a very affordable solution for Bluetooth Low Energy or Bluetooth 4.0. The Bluetooth BLE Module connects with your MCU such as the Arduino through the UART port.
It supports Central and Peripheral mode switching, is easy to modify using AT commands. Ideal to be used with Android and Iphones, PCs, other Arduinos or any other Bluetooth device for wireless serial communication (UART).
This module can be configured in master, slave or master-slave mode.
The Bluetooth module uses the CSR BlueCore or TI CC2541 chip.
The base board comes with polarity reverse protection and a logic level conversion circuit.
The power can be adjusted -23dbm, -6dbm, 0dbm, 6dbm, through an AT Command (AT+POWER).
