{"title":"Bluno - An Arduino Bluetooth 4.0 (BLE) Board","handle":"bluno-an-arduino-bluetooth-4-0-ble-board","url":"/products/bluno-an-arduino-bluetooth-4-0-ble-board","description":"The Bluno integrates a TI CC2540 Bluetooth 4.0 (BLE) chip with an Arduino Uno-compatible development board, enabling wireless communication for your Arduino projects. It supports wireless programming via BLE, Bluetooth HID, AT command configuration, and transparent serial communication.\n\nFully compatible with all Arduino Uno pins, any existing Uno project can go wireless simply by switching to Bluno. DFRobot provides open-source apps for both Android and iOS to communicate with Bluno devices.\n\nKey Features\n\n\nBluetooth 4.0 (BLE) – On-board TI CC2540 chip for low-energy wireless communication\n\nWireless Programming – Upload sketches over BLE without a USB cable\n\nBluetooth HID – Connect as a Human Interface Device to PCs and other devices\n\nAT Command Support – Configure BLE settings via AT commands\n\nTransparent Serial – Seamless serial communication through Bluetooth\n\nArduino Uno Compatible – Drop-in replacement with full Uno pin mapping\n\nMaster/Slave Modes – Flexible Bluetooth role configuration\n\nUpgradeable Firmware – Easily update the BLE firmware\n\n\nSpecifications\n\n\nMicrocontroller: ATmega328\n\nBLE Chip: TI CC2540\n\nBootloader: Arduino Uno\n\nPower: USB or external 7–12V DC\n\nDimensions: 60 × 53 mm\n\nWeight: 30g\n\n\nIdeal For\n\nBLE-enabled wearable and smart device prototyping\nWireless Arduino projects and IoT applications\nBluetooth HID devices (keyboards, controllers)\nAdding wireless connectivity to existing Arduino Uno projects\n\n\n\nNote: Bluno is compatible with other Bluno Family devices only — it does not support third-party BLE devices due to differences in Bluetooth profiles. Disconnect any BLE device before uploading a new sketch.\n\n\nPackage Contents\n\n1× Bluno\n\n\nResources\n\nWiki & Documentation\nBasic Demo Tutorial\nSchematic (PDF)\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":11233,"title":"Default Title","sku":"DF-DFR0267","price":41.21,"on_sale":false,"in_stock":true,"available_quantity":103,"option1":"Default Title"}]}
