Hello, I was recently making a flight computer for a tvc rocket with a t4 controlling it. I soldered the t4 in, but when I tried to pull data from the I2C bus it couldn't find a device. I found this strange so I ran an I2C scanner and the serial output had an error on every address. I was confused so I ran it a few more times and then ran it on a spare uno, which never gave an error. I attempted to connect the uno to the pcb with some headers I included and connected just the 3v, gnd, sea, and scl. After getting nothing from the test, but still getting no errors on the uno, I attempted to power the teensy again and it would not power on. My multimeter is not working, but I tried multiple cables and other devices on the USB port to verify it was still working and I connected another I2C device to the uno to verify the scanner would pick up devices. Any idea what could have caused it? I am happy to provide any more information if needed.
