RE: Purpose of nRF52840 on Thingy:91

Hello Michael,

In general if you run the nRF9160 samples on Thingy:91 they run on the nRF9160.

In our infocenter you can see that:

For Universal Serial Bus (USB), Bluetooth® , and Near Field Communication (NFC) passive tag connectivity, Nordic Thingy:91™ uses a nRF52840 System on Chip (SoC). It is a powerful, highly flexible, ultra-low power SoC that incorporates a Bluetooth Low Energy radio and a 32-bit Arm® Cortex®-M4F CPU.

Please also take a look at the Connectivity Bridge application. It is what normally runs on the nRF52840 on a Thingy:91.

I would recommend looking at the Developing with Thingy:91 in general, there is a section about flashing firmware for both chips and our Cellular IoT Fundamentals course is made for both the nRF9160 DK and Thingy:91.

Best regards,

Michal
