acn52832

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:

  • ADC

  • CLOCK

  • FLASH

  • GPIO

  • I2C

  • MPU

  • NVIC

  • PWM

  • RADIO (Bluetooth Low Energy)

  • RTC

  • SPI

  • UART

  • WDT

See Nordic infocenter [1] 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.
