Product description
Adafruit Feather nRF52 Bluefruit is a complete development board for Bluetooth Low Energy, built around the nRF52832 from Nordic Semiconductor. The board is Arduino-compatible, features built-in USB, and, as usual in the Feather series, includes an integrated connector and charging circuit for LiPo batteries.
In addition to handling Bluetooth LE communication, the nRF52832 also serves as the main processor. Unlike previous versions, it has built-in support for the Arduino IDE — no additional 32u4 or SAMD21 is needed, making the board significantly more power-efficient.
With an ARM Cortex M4F (with floating-point acceleration) running at 64 MHz, 512 KB flash, 64 KB SRAM, built-in USB-to-serial conversion, plenty of GPIO, analog inputs, PWM, and timers, the possibilities are vast.
The board can operate from 1.7 V to 3.3 V and includes an integrated voltage regulator.
