Description : 

The nRF52832 is Nordic Semiconductor’s latest multiprotocol radio System on Chip (SoC). It’s half microcontroller, with a list of features including 32 configurable I/O pins, SPI, I2C, UART, PWM, ADC’s, 512kB flash, and 64kB RAM. And it’s half 2.4GHz multiprotocol radio, supporting Bluetooth Low Energy (BLE), ANT, and Nordic’s proprietary 2.4GHz ultra low-power wireless communication – it even features on-chip NFC tag support.

SparkFun’s nRF52832 Breakout provides easy access to all of the chip’s features. It breaks out all of the nRF52’s I/O pins, provides a 32.768kHz RTC crystal, a user-programmable button and LED, and a trace antenna to send and receive those 2.4GHz transmissions. Plus, to make the chip as easy-to-flash as possible, the breakout comes pre-programmed with a serial bootloader.

Nordic’s nRF52832 is an SoC that combines an ARM Cortex-M4F microprocessor with a 2.4GHz multiprotocol radio. In addition to providing access to all of the chip’s I/O pins, the breakout board includes a handful of external components. The nRF52832 can operate on a power supply between 1.7 and 3.6V. The board also includes a 3.3V regulator with a maximum input of 6V, if you want to power the board with batteries or a regulated wall supply.

Features:

• ARM Cortex-M4 CPU with floating point unit (FPU)
  • 1MB internal Flash -- For all of your program, SoftDevice, and file-storage needs!
  • 256kB internal RAM -- For your stack and heap storage.
• Integrated 2.4GHz radio with support for:
  • Bluetooth Low Energy (BLE) -- With peripheral and/or central BLE device support
  • Bluetooth 5 -- Mesh Bluetooth!
  • ANT -- If you want to turn the device into a heart-rate or exercise monitor.
  • Nordic's proprietary RF protocol -- If you want to communicate, securely, with other Nordic devices.
• Every I/O peripheral you could need
  • USB -- Turn your nRF52840 into a USB mass-storage device, use a CDC (USB serial) interface, and more. This is a big add compared to the nRF52832!
  • UART -- Serial interfaces with support for hardware flow-control if desired.
  • I2C -- Everyone's favorite 2-wire bi-directional bus interface
  • SPI -- If you prefer the 3+-wire serial interface
  • Analog-to-digital converters (ADC) -- Eight pins on the nRF52840 Mini Breakout support analog inputs
  • PWM -- Timer support on any pin means PWM support for driving LEDs or servo motors.
  • Real-time clock (RTC) -- Keep close track of seconds and milliseconds, also supports timed deep-sleep features.
• Peripheral-multiplexing -- (Nearly) any pin can support any of the above features.
