Great !

Is 1x5 sil for ICSP this (in the middle) ?

Are 5 pins required because: 1 for serial (RX) + 2 for i2c + 2 for power ?

I'm thinking again about flow control. If the controller needs to send back
ACK once a command is processed (so you can send next one), maybe it could
be interested to also add a wire for serial/TX ? That would give 6 wires for
this connector, and would allow us to implement this feature later, but with
the same board (a new firmware). What do guys think ?

Maybe not an idea... I'm on the "cheap side", and would expect to be able to
build the board easily without "advanced" tools. SMD components are kind of
advanced or hard to handle for me, could it be possible to avoid this ? I
also build my PCB using photo laser paper and an iron, so the simpler the
PCB is, the better it is for me (large track, with space). But that's for
me, I don't know how other people deals with this. Maybe we could have two
versions: one for the "full of tools" / advanved guy, one simpler,
probabably larger, for the "cheap" guy ? Like for arduino boards ? (one is
double sided, small, another is single sided, bigger, but everybody can
build it)

Cheers,
Seb
