Phytec nRF52840 reel board (Zephyr)

This could be an interesting option to show nearby RuuviTag sensor readings. No WiFi to relay to internet but could store some history and work as a hub on your wall.

nRF52840 chip, e-ink display and running Zephyr.

BTW, @otso have you noticed that Nordic Semi is a Zephyr platinum member? :thinking: I bet we’ll see some great support for their chips in the future.

I hope so, Zephyr has a large community and great support. One missing piece is the NFC drivers: https://github.com/zephyrproject-rtos/zephyr/issues/5703
