M0201 gimbal passthrough pinout

[jon]

Hi, what is the order of the pins for the i2c passthrough on the M0201 board? Assuming something like 5V - SCL - SDA - X - X - GND, but would just like to ask to make sure. I don't believe it's documented anywhere either

Currently facing the same challenge, since I would like to make the changes according to the guide: https://docs.modalai.com/M0153/

@jonathankampia did you figure the pin order out? Or maybe @Alex-Kushleyev could assist us here?

Thanks for the help already in advance!

@Zachary-Lowell-0 and @smiley ,

I just updated the docs to include more info on this https://docs.modalai.com/M0153/#misc-connector-pinout

Also verified that i could ping a i2c device connected to M0201 J4 and M0201 itself is connected to VOXL2 J7 via M0181 (there are other options how to connect M0201 to VOXL).

IMU -> [JST GH cable] -> (M0201 J4) .... (M0201 J2) -> [MIPI COAX cable] -> (M0181 J1) .... (M0181) -> (VOXL2 J7)

voxl2:/$ i2cdetect -r -y 4
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:          -- -- -- -- -- -- -- -- -- -- -- -- --

(able to ping an i2c IMU board connected to /dev/i2c-4).

Please let me know if you have any additional questions.
