The nRF52832 has a ARM Cortex M4F MCU. The Atmel SAM3U2C you mention is a separate MCU mounted on the development kit, and works as a on-board Segger J-Link interface. When you connect to the board via USB, you are communicating with the SAM3U2C, which then handles flashing and debug of the nRF. You can read more about it over on segger's website.

Hi Usman,

I know you haven't asked for third-party modules, but in case it helps. It solves some problems before they became, for example: Bluetooth and regulatory approval and hardware design for the BLE module.

You can find the list for 3rd party modules: https://www.nordicsemi.com/eng/Products/3rd-Party-Bluetooth-low-energy-Modules

Cheers

Hi Jorn

By checking your mentioned documents link above. nRF52832 has cortex-M4 MCU. It using Atmel SAM3U2C MCU. But SAM3U2C is cortex m3.

What is going on?

Hello Usman

The PCA10040 has the nRF52832. Reference circuitry for the chip can be found here, reference layout can be found here, the hardware files for the PCA10040 can be found here, and guidelines for PCB design with the nRF52 series can be found here.

Best regards
