PUREmodules were designed around the Modular Sensor Architecture to make hardware prototypes faster, simpler and easier.  Our goal is to build an ecosystem of hardware that utilizes the Open Architecture as a launching point for your next project.

Arduino Setup for nrf52 Core module

Nordic Tools

Download and install SDK

JLink Drivers

on the command line you can flash hex onto the board via the following command
"nrfjprog --chiperase --program YOURAPPHERE.hex -f NRF52"

SDK setup
modify C:\nRF5_SDK\components\toolchain\gcc\Makefile.windows to point the the right version of GCC
example for version 5.4.0 arm gcc tools this is what it will look like
GNU_INSTALL_ROOT := C:/Program Files (x86)/GNU Tools ARM Embedded/5.4 2016q3
GNU_VERSION := 5.4.0
GNU_PREFIX := arm-none-eabi

You will need a softdevice with your hex file if you are using the BLE stack from nordic, the simplest way to to this is with merging the softdevice and your hex, then you can flash just one hex file. 

Here is what my bat file looks like for flashing code:
mergehex -m C:\nRF5_SDK\components\softdevice\s132\hex\s132_nrf52_3.0.0_softdevice.hex ./_build/nrf52832_xxaa.hex -o nrf52832_s132.hex
nrfjprog --chiperase --program nrf52832_s132.hex -f NRF52 -r
