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

I suggest making a breakout board of some kind for your other chips where the SWD pins are accessible, (either one, where the chips can be replaced easily, or one for each chip) as there is no good way to easily replace just the chip on the DK. In the DK user guide, you can see how to program external boards using your DK.

When making a breakout board, you need the peripheral components from the reference circuitry in the PS to ensure proper operation from the nRF52840.

Best regards,

Simon

Hi Simon,

Thanks for your help. How would you suggest making the breakout board with the nRF chips? Would you recommend using a PCB design to accommodate the chip? If so, are there example PCB designs for the nRF chips available online?

I was looking through the DK user guide but was not able to find how to program external board. Where exactly in the user guide is this information provided? 

Thanks for your help,

Dylan
