PCBs come in all different levels of complexity.
Nordic has a serial-over-ble profile, but it is not standard like RFCOMM.
I've never tried it.
And I would assume for pedalogical purposes a bare transistor would be preferred rather than the '2008 with its extra diodes and base resistor.
This is how humans work, and this is why I am reading the comments.
