Flora Wearable Bluefruit LE Module [Discontinued]

The Adafruit Flora Bluefruit LE makes it easy to add Bluetooth Low Energy (BLE) to your wearable FLORA projects. All it takes is sewing four traces (or soldering four wires) and you’re ready to connect wirelessly to a phone or tablet.

You can get started quickly using the Bluefruit iOS or Android app, which lets you prototype interactive controls in minutes. The app includes tools like a colour picker, sensor data inputs (including quaternion/accelerometer/gyro/magnetometer and location (GPS)), plus an 8-button game pad for simple remote control.

For more advanced projects, it supports the Nordic UART RX/TX profile, acting as a transparent wireless data pipe between your FLORA and an iOS/Android device. You can use Adafruit’s apps or write your own to communicate with the UART service.

It can also be configured to act as an HID keyboard, a BLE heart rate monitor (with added pulse-detection circuitry), or a UriBeacon that broadcasts a URL. It includes over-the-air bootloading, allowing firmware updates from an Android or iOS device. This uses the same module and firmware as the BLE UART Friend, but in a rounded shape, and it does not include hardware flow control pins—making it best paired with a microcontroller that supports hardware serial, such as the FLORA.
