- ARM Cortex M4F (with HW floating point acceleration) running at 64MHz
- 512KB flash and 64KB SRAM
- Built in USB Serial converter for fast and efficient programming and debugging
- Bluetooth Low Energy compatible 2.4GHz radio (Details available in the nRF52832 product specification)
- FCC / IC / TELEC certified module
- Up to +4dBm output power
- 1.7v to 3.3v operation with internal linear and DC/DC voltage regulators
- 19 GPIO, 8 x 12-bit ADC pins, up to 12 PWM outputs (3 PWM modules with 4 outputs each)
- Pin #17 red LED for general purpose blinking

The Power of Bluefruit LE
The Bluefruit LE module is an nRF52832 chipset from Nordic, which can be used as both a main microcontroller and a bluetooth low energy interface. For most people, they'll be very happy to use the standard Nordic UART RX/TX connection profile - code is provided! In this profile, the Bluefruit acts as a data pipe, that can 'transparently' transmit back and forth from your iOS or Android device. You can use our iOS App or Android App, or write your own to communicate with the UART service.
The board is capable of much more than just sending strings over the air! Thanks to an Arduino wrapper library, 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.
Use the Bluefruit App to get your project started
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. This data can be read over BLE and processed directly by the nRF52 microcontroller
You can do a lot more too!
- The Bluefruit can also act like an HID Keyboard (for devices that support BLE HID)
- Can become a BLE Heart Rate Monitor (a standard profile for BLE) - you just need to add the pulse-detection circuitry
- Turn it into a Beacon, the Google standard for Bluetooth LE beacons. Just power it and the 'Friend will bleep out a URL to any nearby devices with the nRF Beacon app installed.
- Built in over-the-air bootloading capability. Use any Android or iOS device to get updates and install them via the Nordic OTA app (or the Adafruit app). This will update the native code on the BLE module, and is an alternative to the USB-serial bootloader
Comes fully assembled and tested, with a USB bootloader that lets you quickly use it with the Arduino IDE. We also toss in some header so you can solder it in and plug into a solderless breadboard. Lipoly battery and MicroUSB cable not included (but we do have lots of options in the shop if you'd like!)
