Hello,
The XIAO ESP32S3 (Sense) boards stacked on top of each other through direct connection of their B2B connectors is not ideal for my project.
Is it possible for the boards to be connected with a B2B connector extension cable (if possible please provide a link to the the extension cable) or is there another solution?
Thank you.
Have you figured out the solution? Maybe they use some kind of a standart there?
Welcome,
i dont think a ribbon cable is in the plans… the B2B connector is too small you can design yourself a daughter board… I am not sure what space control you are under but this is about the best you can get
Hi there,
So, it should be fine for a short cable but beware!
On the XIAO ESP32S3 Sense, the B2B isn’t just “a few GPIOs” – it carries:
Those camera and SD signals run in the tens of MHz range (e.g. 20–40 MHz clock edges). The board and connector were designed assuming the Sense board is directly stacked – essentially zero extra trace length.
So electrically, that B2B is a high-speed parallel bus, not a low-speed “TTL I/O header”.
Your out on the Bleeding edge here so expect some cuts, 
You can probably order a custom ribbon cable, but AFAIK nothing like it exists on seeeds website.

Check out the MORE I/O thread for the PCB I made for it.
