with the introduction of more i2c-talking modules it is becoming more of a problem to connect them all to the same network.
there are various solutions-- more headers on a ribbon cable, daisy-chaining by having multiple headers per module, or a little bus PCB which is basically a mult.
and here it is mounted to TT:
they are very cheap to make, but not worth having the circuit assembler do a big batch. i’ll offer them pre-assembled (by hand) sometime next week (price tbd), but i’d like to post sources now, so people can order and build their own if desired. in fact, if people want to order a bunch and resell them here i’d be totally happy for that.
osh link ($4.70 for 3 boards)
2x3 female header: Sullins PPTC032LFBN-RC
2x3 right angle male headers (4 required): Amphenol FCI 68021-406HLF
there are equivalent parts and sources for these-- please post your own part numbers and sources if you have them.
incredibly easy first soldering project.
aside: if you want to make your own 6 pin ribbon cables, sparkfun has crimp headers: https://www.sparkfun.com/products/10651
