View Full-Size Image


Bluno Bee is a serial to bluetooth 4.0 module, it adopts XBEE form factor which is compact and is compatible with all shields with XBEE socket.  Bluno Bee is designed to have voltage regulator which supports both 5V and 3.3V MCUs.

Bluno Bee can talk to your Arduino serial port , and able to turn your arduino to bluetooth 4.0 (BLE) ready instantly.  Simply get anArduino IO Sensor Expansion Shield and plug this module to xbee socket, you have an Arduino BLE ready board.

With two Bluno Bee, two arduino are able to communicate with each other via Bluetooth.  You can enjoy features like point-to-point wireless transparent transmission, master-slave machine setting, wireless code (sketch) uploading and HID connection with PC.

For more compact size or want an all in one arduino ble board, we recommend our Bluno series,  they are based on Arduino Unoor Arduino Mega and with Bluetooth 4.0 (BLE) build-in, they are more cost effective and compact.  


We've also developed Apps (Play Bluno) on both Android and IOS platform for you to start playing between phone and arduino immediately. At the same time, we provide developers more freedom and support: users can not only debug Bluno through AT command, but also update BLE chip firmare via USB.

It is suitable for applications like wearable device, for example a smart pedometer bracelet with Arduino + Android/IOS. By linking into star network of low power consumption, BLE achieves rapid real-time communication.
**Mobile operating systems including iOS, Android, Windows Phone and BlackBerry, as well as OS X and Windows 8, natively support Bluetooth low energy. The Bluetooth SIG predicts more than 90 percent of Bluetooth-enabled smartphones will support the low energy standard by 2018.
