Adafruit Feather nRF52 Bluefruit LE - nRF52832

Bluefruit: a BLE module and development board combined!

The Adafruit Feather nRF52 Bluefruit LE development board allows you to create a Bluetooth-controlled electronic project on your smartphone or tablet. Ultra-lightweight, it is 100% compatible with the Arduino programming environment and can be used with all Adafruit Feather modules: datalogger, WiFi, radio, etc. The only exception is the Feather UART modules, for example the GPS module.

To make sure you’re able to develop any Bluetooth Low Energy project you might think of, the board includes a very comprehensive pinout (PWM, GPIO, analogue inputs, etc.), a bootloader with a reset function, a LiPo 3.7V battery connector and, of course, a USB port for programming on Arduino. There is also a free app (iOS and Android) you can use to control your BLE project, which includes a colour picker, directional pad, GPS, etc.

A new more economical, simpler and more powerful version!

The Adafruit Feather nRF52 Bluefruit LE board has twice as much SRAM and flash memory as the previous modules equipped with the nRF51 chip. The system is built around the nRF52832 chip, which can be programmed directly from the Arduino IDE like a microcontroller, which means even more energy savings for you.
