| 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 `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. |
