Flashing nRF Chips on a single Development Kit

[Dylan V]

Hi,

I recently purchased a DK as well as 5 nRF52840 chips. I have been working on flashing some code on the development kit. I would like to also flash this code on every other nRF chip, however, I saw that the chip on the DK is soldered directly on the kit. I initially thought that the chips on the DK would be easily removable to be able to flash and test multiple chips. 

Is there any way for me to test my code on multiple chips/flash it on using the development kit?

Thanks,

Dylan

Hi Dylan

For PCB design, please see the Hardware and Layout section of the product specification, as well as this application note on circuit board guidelines for aQFN packages (nRF52840s package format).

Please see section 8.10 Debug Output in the user guide. You can either use the 10-pin debug header P19 or the P20 header, connected to an external board like the picture below.

Best regards,

Simon
