Do I need a programmer to program NRF523832 in the DK, Can I just program it through USB?

This is On-Board version of famous J-Link Programmer/Debugger.</p> <p>So just plug in the USB and you can program nrf52 chip easily.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/56624?ContentTypeID=1Wed, 29 Jun 2016 11:10:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e9e6572f-9ca1-47f0-9586-27cf6c583843Petter Myhre<p>PCA10040 is not a chip, it identifies the PCB, that this is a nRF52 DK.</p> <p>The label that PCA10040 is printed on is an interface MCU that can program the nRF52832 chipset.</p> <p>See <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52/dita/nrf52/development/nrf52_dev_kit.html?cp=2_0">this</a> for more information.</p><div style="clear:both;"></div>
