Adafruit Feather nRF52 Bluefruit LE - nRF52832

Description

• The Adafruit Feather nRF52 Bluefruit is an easy-to-use all-in-one Bluetooth Low Energy board, with a native-bluetooth chip, the nRF52832! It's our take on an 'all-in-one' Arduino-compatible + Bluetooth Low Energy with built in USB and battery charging.
• This chip has twice the flash, SRAM and performance of the earlier nRF51-based Bluefruit modules. Best of all it has Arduino IDE support so there is no 'helper' chip like the ATmega32u4 or ATSAMD21. Instead, this chip is programmed directly! It's got tons of awesome peripherals: plenty of GPIO, analog inputs, PWM, timers, etc. Leaving out the extra microcontroller means the price, complexity and power-usage are all lower/better.
• It allows you to run code directly on the nRF52832, straight from the Arduino IDE as you would with any other MCU or Arduino compatible device. A single MCU means better performance, lower overall power consumption, and lower production costs if you ever want to design your own hardware based on your Bluefruit nRF52 Feather project!
• The chip comes pre-programmed with an auto-resetting bootloader so you can upload quickly in the Arduino IDE with no button-pressing. Want to program the chip directly? You can use our command line tools with your favorite editor and toolchain.
• The example code works great with Adafruit's existing iOS and Android app.
