Description: Bluno BLE Bluetooth 4.0 - compatible with Arduino
Bluno is fully compatible with popular module Arduino Uno. This means that it can be programmed through the Arduino IDE using available libraries. The so-called Arduino Shield are also collaborating with the DFRobot module.
The board has a CC2540 chip by Texas Instruments which allows for communication in the Bluetooth 4.0 standard. Thanks to this functionality, the user can remotely program the Bluno (BLE) module, use AT commands and to update the software in a simple way.
The board contains the ATmega 328 microcontroller, equipped with 14 digital inputs/outputs, 6 of which can be used as PWM outputs (e.g. for motor control) and 6 as analog inputs. The system works with the clock signal with the frequency of 16 MHz. The module has also a USB connector, DC power socket, RESET button, and the leads used to connect the AVR programmer.
DFRobot company introduced colored connectors that facilitate the identification of the leads:
- red- power pins,
- blue - analog pins,
- green- pins digital.

In order to start Bluno, it is necessary to connect the system to computer usingmicroUSB cableand choose inthe Arduino IDE, the Arduino Uno board. |
Power
The module can be powered via the USB cable and the external device, for example, the AC adapter, the battery or the rechargeable battery. Switching the power sources is automatic. The power supply is connected to a standard DC connector. Rechargeable battery or other source is connected to the pins of the POWER connector.
Programming
Creating and installing the software is allowed by the free environment of the Arduino IDE. Implemented bootloader allows you to send the program directly via USB cable. ISCP connector enables connection of an external AVR programmer. Bluno also has the capability of remote programming via Bluetooth (BLE).
