Feather nRF52 Bluefruit LE nRF52832

Description

Feather nRF52 Bluefruit LE nRF52832 is an easy to use Bluetooth Low Energy board, based on the nRF52832 bluetooth chip. This chip has twice the Flash, SRAM, and performance of the previous nRF51 based Bluefruit modules. Best of all, it has Arduino IDE support, so there is no need for a 'helper' chip like the ATmega32u4 or ATSAMD21. Instead, this chip is directly programmable! It has lots of GPIO, analog inputs, PWM, timers, etc. By not needing an extra chip, the price, complexity, and power consumption are all lower/better. This allows you to run code directly on the nRF52832, straight from the Arduino IDE, just like you would with any other MCU or Arduino compatible device.
