Adafruit Bluefruit LE SPI Friend - Bluetooth Low Energy (BLE)

Adafruit Bluefruit LE SPI Friend - Bluetooth Low Energy (BLE)

Regular price $0.00 $23.96 Sale

Key Features:

  • Add Bluetooth Low Energy connectivity to anything with 4 or 5 GPIO pins
  • Built in over-the-air bootloading capability so we can keep you updated with the hottest new firmware
  • The Bluefruit can act like an HID Keyboard (for devices that support BLE HID)
  • Full control over how the device behaves, like the ability to define and manipulate your own GATT Services and Characteristics, or change the way that the device advertises itself for other Bluetooth Low Energy devices to see.

Would you like to add powerful and easy-to-use Bluetooth Low Energy to your robot, art or other electronics project? Heck yeah! With BLE now included in modern smart phones and tablets, its fun to add wireless connectivity. So what you really need is the new Adafruit Bluefruit LE SPI Friend!

The Bluefruit LE SPI Friend makes it easy to add Bluetooth Low Energy connectivity to anything with 4 or 5 GPIO pins. With SPI, you don't have to worry about baud rates, flow control, or giving up a hardware UART port. Connect to your Arduino or other microcontroller using the common four-pin SPI interface (MISO, MOSI, SCK and CS) plus a 5th GPIO pin for interrupts (to let the Arduino know when data or a response is ready).
