[Thread] Sensors are giving out garbage values

[frroossst]

I was testing the Teensy with only the BMP280 and KX134 and the sensors are giving out garbage values, am figuring out if it is a Teensy issue, a sensor issue or a code issue. Most probable is a sensor issue, but they're new so ¯_(ツ)_/¯

No I2C devices found

The wiring seems correct so don't know why that is.

Apparently using the ground pin on the right hand side while also having 3v3 and 5v plugged in doesn't work?! and you need to use the ground on the other side of the board, this stops the unknown error warnings, but still no I2C devices show up

After some panic, I think I know what went wrong here, will do more testing and confirm by EOD

Sensors work as intended, false alarm.

Didn't solder the power and I2C pins properly on the teensy, smh.
