V4.5 standard pcb voltages

Hardware PCB

Hi,

I have just powered up my standard v4.5 for the first time and I’m following andyinv’s useful test thread. I have 5V at all the test here points on the back of the pcb but cant see any points to test for 3.3V. Does this board have any 3.3V to test?

When you plug the teensy to the board it will power the IMU with its 3.3v
Board itself doesn’t have 3.3v supply

Only the micro v4.5 version has 3.3V !

Teensy is powered with 5V, and has its own 3.3V supply outputs (2x)
