Thingy external connection

[Sheldon]

In order to connect an external sensor to the available pins, will we need to create our own version of the FW in order to communicate with the sensor? Or are there generic methods to communicate?

Adafruit Feather nRF52 Bluefruit LE - nRF52832 has what I was hoping the Thingy:52 had, an Arduino wrapper to write simple sketches to be uploaded and executed.
