I must have searched the wrong terms since I can't imagine I'm the first to ask the question. According to the data sheet the processor in the TeensyLC can operate from 1.7 to 3.6V Vcc.

I found reference to supply voltage ranges for other Teencys here but nothing about the TeencyLC
https://www.pjrc.com/teensy/external_power.html
I want to communicate, over I2C, with a 2.8V sensor (VL53L0X) . I think there is a trace on the bottom of the TeensyLC that connects the USB Vcc to the Vin pin. Is there a problem with cutting that trace and connect 2.8V to Vin?
I think that the 3.3V supply on the TeencyLC board will not work.
Will there be any other problems?
If this works will I be able to connect the SDA, SCL Xshut and GPIO pins directly between the VL53L0X and the TeencyLC?
Even though the SDA and SCL may be 3.3V tolerant (according to some sources) it appears that XShut is not. A really clean design would include level shifters but If I understand correctly I can eliminate all of that if I can run the TeencyLC at 2.8V
Thanks in advance for any help you can give.
