It&#39;s different on each softdevice version.&nbsp;</p> <p><img src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/7080.pastedimage1644246111758v1.png" alt=" " /></p> <p>Regarding the device hardware revision, you can read the FICR to find the info, see <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/ficr.html?cp=4_2_0_12_0_16#register.INFO.VARIANT">here</a>.&nbsp;</p> <p>Same with device serial number, you can read <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/ficr.html?cp=4_2_0_12_0_2#register.DEVICEID-0">here</a>.</p> <p>It&#39;s not possible to read the chip to know which board it&#39;s located on. It&#39;s the info included in the serial number of the Segger chip located on the board. For example, from my experience, if it starts with 682 it&#39;s the PCA10040.&nbsp;</p><div style="clear:both;"></div>
