The best place to start is to add it to the maker editor. See [https://maker.makecode.com/boards/add-a-new-board](https://maker.makecode.com/boards/add-a-new-board) . It will allow you to test your board in a makecode editor… without having to roll out a new editor.

Thanks @peli for helping to support nRF52840.
I had more success using SAMD51 than STM32.
I am trying to play with nRF52840 right now.

Blinky worked so far on the Feather nRF840 Express. I had some issues compiling for nRF840 dongle (pca10059) and Circuit Playground Bluefruit.
