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).

If you like Serial communication more than SPI, we also have a version that can talk UART

The board is capable of much more than just sending strings over the air! Thanks to an easy to learn AT command set, you have full control over how the device behaves, including 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. You can also use the AT commands to query the die temperature, check the battery voltage, and more, check the connection RSSI or MAC address, and tons more. Really, way too long to list here!

Download our free Android/iOS app and you're ready to rock!

Using our Bluefruit iOS App or Android App, you can quickly get your project prototyped by using your iOS or Android phone/tablet as a controller. We have a color picker, quaternion/accelerometer/gyro/magnetometer or location (GPS), and an 8-button control game pad.

  • Transport: SPI at up to 4MHz clock speed
  • 5V-safe inputs (Arduino Uno friendly, etc.) On-board 3.3V voltage regulation
  • Bootloader with support for safe OTA firmware updates
  • Easy AT command set tunneled over SPI protocol to get up and running quickly
