For v3.0:
For v1.1, v1.2, v2.1, and v2.2:
Just do the same wiring if you want to add the L2 and R2 buttons.

What about ZL and ZR (L2 and R2)?
What do I wire ground to on 2.2?
You wire those to the L2 and R2 pads, just under the L1 and R1 pads.

You can use any GND as they are all the same and connected.
can a L2 and R2 be wired up on the tinkerBOY Controller v3.0 and if so how would one do this?
