nRF52840 VS nRF5340 - difference

[hank1]

Hello, This is QM33120WDK1 user. (nRF52840 dk + antenna board)

I am using IEEE 802.15.4 for UWB positioning protocol

When I opened it, I could check there are nRF52840 chip and nRF5340 chipset on the nRF52840 dk board.

What is their role of each chipset?

I need only IEEE 802.15.4, not bluetooth.. or something

Maybe one allow to upload via J-Link?

Thank you
