برد توسعه NRF52832

Description:
The NRF52832 is Nordic Semiconductor's latest multiprotocol radio system-on-chip (SoC).
The NRF52832 is 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.
It meets the challenges of a broad range of applications that need advanced Bluetooth® LE features, protocol concurrency and a rich and varied set of peripherals and features. In addition, it offers generous memory availability for both Flash and RAM.
The NRF52832 is multiprotocol capable with full protocol concurrency. It supports Bluetooth Low Energy, including the high-speed 2Mbps feature. Bluetooth mesh can be run concurrently with Bluetooth LE, enabling smartphones to provision, commission, configure and control mesh nodes. NFC, ANT and 2.4 GHz proprietary protocols are also supported.
It is built around an Arm® Cortex™-M4 CPU with floating point unit running at 64 MHz. It has NFC-A Tag for use in simplified pairing and payment solutions. It has numerous digital peripherals and interfaces such as PDM and I2S for digital microphones and audio.
Exceptionally low energy consumption is achieved using a sophisticated on-chip adaptive power management system.
