The 3.3V pin on Teensy can only take a regulated 3.3V if feeding that.

Since it wasn't stated ... had to ask given the use of 5V - could have been an AVR Teensy - otherwise it makes no sense to use 5V for an input when while 5V tolerant - it is a device designed for 3.3V usage.

What Teensy is in use? Is it one that is 5V tolerant?

Great! Also easy to use :: #define WIRE WIRE2
Not sure where those pin numbers came from they don't seem to match any 32 bit Teensy card. The T_3.5 and 3.6 can use ALT WIRE on pins 7&8.

The 1170 package is : LFBGA289 and 14 mm x 14 mm, 0.8 mm pitch
There was a note IIRC the board would have to be bigger just to hold the...
As noted those pins are for Wire2
So all the WIRE commands need to use WIRE2 not WIRE
That should select the right internal hardware to connect those pins.
