Oh, so I need a level converter for each of the wires. What do the arrows mean? Also, yea it is a 5v arduino. I can just use this right, I can just connect this after connecting it to the buck converter: https://www.amazon.com/gp/product/B07LG646VS/ref=as_li_qf_asin_il_tl?ie=UTF8&tag=circuitdesola-20&creative=9325&linkCode=as2&creativeASIN=B07LG646VS&linkId=5fab3a85ad6f788b6b94f6222416b8a2
Why not? They are absolutely required. Either the pullups are there, or they are not there and it won't ever work.
You need to be CERTAIN.
Why have you not posted a link to the IMU product page?
Why are you using a 3.3v converter and the 3.3v I2C connections when the device has specific connections for 5v?
On this site it says: 3.3V and 5V compatible (We have included logic level shifters for 5V use)
So I thought i didnt need them. I have to use i2c anyway instead of spi because the barometer only works through i2c. BerryIMU v3 - An accelerometer, gyroscope, magnetometer and barometric/altitude sensor - ozzmaker.com
Which means you can use the 5V from your arduino and connect to the 5V portion of the IMU (VCC/SCL/SDA) and use the internal pullups of the arduino on SDA/SCK.
But who knows how you really have it wired up vs. random pictures from the internet that may or may not accurately represent your setup
So if I just connect it to the 5V on the IMU, I don't need any extra physical components like a pullup resistor or a logic level converter?
