The nRF52832 is Nordic Semiconductorâ€™s latest multiprotocol radio System on Chip (SoC). Itâ€™s half microcontroller, with a list of features including 32 configurable I/O pins, SPI, I2C, UART, PWM, ADCâ€™s, 512kB flash, and 64kB RAM. And itâ€™s half 2.4GHz multiprotocol radio, supporting Bluetooth Low Energy (BLE), ANT, and Nordicâ€™s proprietary 2.4GHz ultra low-power wireless communication â€“ it even features on-chip NFC tag support.
SparkFunâ€™s nRF52832 Breakout provides easy access to all of the chipâ€™s features. It breaks out all of the nRF52â€™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.
Nordicâ€™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 chipâ€™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.
