{"title":"ELE BlueTooth Shield-V1.2","handle":"ele-bluetooth-shield-v1-2","url":"/products/ele-bluetooth-shield-v1-2","description":"The ELE Bluetooth Shield V1.2 adds wireless serial communication to your Arduino or Crowduino via Bluetooth V2.0+EDR. Simply stack it onto your board, select two digital pins (D0–D7) for software serial, and start sending data wirelessly at up to 3 Mbps.\n\nBuilt around a CSR Bluecore 04-External chip with Adaptive Frequency Hopping (AFH), this shield supports both Master and Slave modes with a configurable baud rate and AT command set. It provides reliable communication up to 10 m indoors.\n\nKey Features\n\n\nBluetooth V2.0+EDR – Up to 3 Mbps modulation with 2.4 GHz radio transceiver\n\nArduino Compatible – Standard shield form factor for Arduino, Crowduino, and Seeeduino\n\nFlexible Serial Pins – Choose any two pins from D0–D7 for software serial\n\nMaster/Slave Modes – Configurable via AT commands\n\nOn-Board PCB Antenna – No external antenna required\n\n5 Analog I/O Expansion – Additional analog pins for connecting other devices\n\n\nSpecifications\n\n\nBluetooth Version – V2.0+EDR\n\nDefault Baud Rate – 38400\n\nData Format – 8 data bits, 1 stop bit, no parity\n\nDefault PIN Code – 0000\n\nRange – Up to 10 m (indoors, without obstacles)\n\nInterface – UART (TTL)\n\n\n\nNote: Master and Slave devices can pair with each other, but two Master devices or two Slave devices cannot pair together. Slave mode can pair with PCs, phones, and other Bluetooth hosts.\n\n\nPackage Contents\n\n1× Bluetooth Shield V1.2 (assembled)\n\n\nResources\n\nWiki & Manual\nArduino Library\nSoftware Instructions (PDF)\nBluetooth Module Datasheet (PDF)\nHC-05 AT Command Set (PDF)\n","vendor":"Elecrow","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":4044,"title":"Default Title","sku":"EC-MCS01108S","price":26.73,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":104,"option1":"Default Title"}]}
