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!

Hi @18257581 Sometimes our newer boards are lacking in full documentation, so thanks for your patience. We have not publicly posted our uCoax pinouts and not...

ModalAI Forum (forum.modalai.com)

Please refer to this post for the pniout guide on the m0201

@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

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

Please let me know if you have any additional questions.
