Overview
********
The acn52832 is a module in a small form factor which features the Nordic Semiconductor
nRF52832 ARM Cortex-M4F CPU and the following devices:
* :abbr:`ADC (Analog to Digital Converter)`
* CLOCK
* FLASH
* :abbr:`GPIO (General Purpose Input Output)`
* :abbr:`I2C (Inter-Integrated Circuit)`
* :abbr:`MPU (Memory Protection Unit)`
* :abbr:`NVIC (Nested Vectored Interrupt Controller)`
* :abbr:`PWM (Pulse Width Modulation)`
* RADIO (Bluetooth Low Energy)
* :abbr:`RTC (nRF RTC System Clock)`
* :abbr:`SPI (Serial Peripheral Interface)`
* :abbr:`UART (Universal asynchronous receiver-transmitter)`
* :abbr:`WDT (Watchdog Timer)`
See `acn52832 website`_ for more information about the board and `Nordic infocenter`_ for more
information about the SoC.
Hardware
********
Additionally to the SoC the board provides an on-board antenna with a RF matching circuit,
two external oscillators with 32 MHz and 32.768 kHz, load capacitors, a tag-connector
and a RGB-LED.
