Title: Daisy Chainable I2C Extension Boards
Post by: t0mpr1c3 on February 02, 2014, 06:11:32 am
I finally got around to documenting one of the I2C boards I had made: a simple 1-3 splitter.

I'll eventually get around to add more boards to this thread as I write them up. The design thread is here. (http://http://dangerousprototypes.com/forum/viewtopic.php?f=19&t=6003h)

Cool idea!  It might be nice if one of the connectors was moved in more, so you could chain boards together with no gap between the boards.  Like this:

Maybe move the connectors to the back side so the SMT components on top don't get in the way.
