Microduino-Shiedl BT4.0 module is a plug-in device that supports Bluetooth 4.0 low energy standard.
Microduino-Shield BT4.0 module is a bluetooth serial port transparent transmission module, use the 27 PIN standard Microduino interface, support the Arduino board and derivatives, such as Microduino core.
The module is designed by player ogre_c.
Microduino-BT
- Microduino Shield BT, two versions are provided: BT2.1 and BT4.0
- support BT 2.1/4.0 protocol
- use hardware serial or software serial ports (optional)
- UPin-27: Microduino standard interface
- Microduino-Shield BT4.0 use U type 27 PIN interface of Microduino, combines with other Microduino modult to use;
- Microduino-Shield BT4.0 use the HM-10 BLE as the bluetooth core module;
- TI CC2540 chip with 256Kb space;
- Support AT command,the serial baud rate, device name, matched passward can be changed, easy to use;
- Small, cheap, stackable, opened platfrom;
- Open source hardware circuit design, compatible with the Arduino IDE development environment for programming;
- Defines unified interface Microduino specification and contain rich peripheral modules. Set up the quick connection with other Microduino modules and sensors easily and flexibly.
- 2.54 pitch row female connector for easy integration into breadboard.

- Transmission rate:
Asynchronous: 6 kbpsï¼›
Synchronous: 6 kbpsï¼›
Two states:
Flashing means module powered, no matched.
Lighting means module has matched and can start communication.
You can know the module's state by the indicator, easy to use.
