@brolly759 I agree but we also have to assume there are users who, for various reasons cannot or don't want to do soldering. Personally, I would also prefer a smaller connector, but we do want to keep both scalability (MYSX is backwards compatible) and simplicity in usage and sourcing.
I completely understand that the MYSX concept is less than ideal in your application. Perhaps you could include the footprint for one of the smaller versions of it and keep it nonmounted for those who may have daughterboards with MYSX connector at the lower edge or something like that. I think it is @hek that have to decide the amount of fragmentation we want in MySensors affiliated board offerings.
I also want to be clear that feedback on the MYSX concept is always welcome. If there are other connectors suitable we will definitely take them into consideration, but whatever connector we use has to be scalable. So a daughterboard with a small connector should be attachable to a motherboard with a bigger connector and so on, so connectors which are terminated at the ends won't work.

I added the 256 encryption on A3 using the SOT23 package.

@Anticimex the "daughterboard" is only to add extra sensors? What I am building was supposed to be a limited hardware but still expandable "sensor kit" that's main focus on pre-programming, low power, small size and snap in place ease. I guess you could have 2 product lines... Polished all set hardware and just program and set in place or a tinkerer set. Wonder what could sell better on kickstarter ;)

Anticimex

@brolly759 No, the "daughterboard" is also potentially a power source or an other processing unit. I agree that it is a somewhat different product line, but I also maintain that we should try to collaborate with all hardware affiliated with MySensors. It serves no one that we try to compete with each other ;)
And besides, I am not sure kickstarter approves projects capitalizing on open source hw/sw projects ;)

And what do you mean by adding 256 encryption? The atsha204a is a signing/hashing device, not an encryption device.

@brolly759

Just to verify, you plan to release your board under a OSH license right?

brolly759

@Anticimex Yes I meant the atsha204a. Typing too fast while I am at work :)

@hek welcome to the discussion! OSH would require me to source all files I am assuming. What other alternatives are there besides OSH. Obviously these business discussions can be discussed in private ;)

No one except the market! ;)

@BulldogLowell True, but MySensors is not about profit. It's about fun and learning :)

Not sure if you've misunderstood the ideas behind the MySensors project.

MySensors is centered around sharing open source and hardware. We try to help the community members to build cheap and tinker-able home automation components here.

All MySensors hardware is and will be released under an OSH license. This gives everyone the right to create their own derivate work of it if they want. Any company can take our designs and produce large batches if they want. But they cannot use the MySensors logos or trade marks on them.

To pay for the expenses we actually have when designing new boards (component, prototypes), scouting new sensors and the hosting the servers, we rely on donations from kind community members, affiliate links on the "shop" and a tiny margin on the MySensors-labeled stuff sold through ITead.

We're simply not in it for the profit. Just for the fun of it.

That said, you are free to create whatever you want. But you're not allowed to promote it here if it is closed hardware/commercial.

If you do want to co-operate with us, that is, share components and designs, there is a special git-repo with parts and KI-cad goodies here:
