Setting up an i2c port on a FC without an i2c port?


I have a naze32 rev6b thin board that does not have an i2c port/pads. The reg rev6b does, but nada for me. I would like to use an i2c device with inav. I have read in a couple spots that uarts will auto connect/configure i2c devices.. but just like an i2c port, I don't have a uart3...

So, can I use any uart? Softserial port? Do I have to do any cli commands? Also, sda to rx or tx?

Any help would be awesone, thank you

If its the Diatone Thin Naze32 Rev6b, it should have i2c as its based off regular naze32 rev6b ( http://www.dronetrest.com/uploads/db...657a292b5b.jpg ). I cannot find pinout of the diatone board anywhere but i guess it will be on the connector i circled

My best guess is that U2TX and U2RX will be I2c

SDA = TX Data SCL = RX Data. BTW it was just my educated guess and there is almost nothing about this board online. I am sure you can use softserial as it has nothing to do with i2c. I have never used cleanfilght (only betaflight) but i am sure you have to set it up first.

i just did a very quick research and it looks like it will autodetect MAG and BARO (if that's what you are connecting via I2C)
