Bluetooth Module V4.0 CC2541 (Android&IOS BT-09)

BT-09 Bluetooth 4.0 Module(HM-10 compatible)

This BLE Bluetooth 4.0 CC2541 Wireless Module is a BLE module for an embedded system to get BLE wireless communication with BLE-capable devices (e.g. Android, iPhone, and iPad).

It is fully configurable by a rich and well-documented AT command set and allows transparent data communication via serial UART (default baud rate 9600bps).

The Bluetooth4.0 HM-10 is a breakout board for cc2541, it broke out the LED pins, RX/TX, and also added the voltage regulator that regulates 5v to 3.3 v.

HM-10 and HM-11 series Bluetooth modules use a TI CC2540 chip, configure 256KB space, and support the AT command. Users can change the role (master, slave mode) and the serial port baud rate, equipment name, matching password, and other parameters on demand. It is very flexible to use.

The most complete, most convenient, and most stable Bluetooth data transmission, remote control, and data acquisition module. Master-slave in one, transparent transmission, replacing the serial port. Remote control, transparent transmission, and MCU are unnecessary. Remote data acquisition, transparent transmission, and MCU are unnecessary.

Application for BT-09 Bluetooth Module:

Although this BT-09 Bluetooth Module with a breakout board can be used for a near-endless number of different Electronics projects, it shows its true value when used for applications in which power consumption is a serious concern. Within such projects, it allows for devices, controller boards, users, and even other Bluetooth modules to communicate seamlessly. This opens up many new possibilities for home automation, wireless access, and control, as well as monitoring, tracking, or reactive services that keep you updated with vehicle locations, data usage, or any other important bits of info.
