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.

FWIW, the “RTC” (based on the 32.768 crystal) is a “Real Time Counter”, NOT a “Real Time Clock”. (This explains why there’s no provision for a backup battery connection, usually labeled “Vbat”.)
I’m sure some will still find this board useful, but personally, I have no need for Bluetooth at the moment.
Does the Arduino Bootloader peacefully coexist with the Nordic ‘softdevices’ (ie, S212 & S332)? Is it replaceable/restoreable through the SWD interface?
The boards ship out with the S132 soft device installed, and the bootloader should be able to update that image if you need.
The bootloader on our board is a slightly modified version of Nordic’s nRF5 v11.0.0 SDK HCI/UART bootloader (source can be found here). Using nrfutil v0.5.2, you should be able to package up and upload an application, SoftDevice, or even a new bootloader.
There’s lots of good info on creating an image to bootload and running the bootloader over on Nordic’s SDK reference page. Our Arduino hardware definitions can at least help get you started, though.
