Some components we have decided:<br>

Yes, we could easily build it. We have two chip antennae and
they have the same dimensions</div>

module and one antenna chip.</div>

<div>But it raises the board cost by ~20 EUR.</div>
<div><br>
</div>
<div>That is something which is unclear. Should we force the
cost to stay down or get the features up?</div>
<div>Especially as this is a limited edition. But we can’t build
it to order. We have to decide.</div>
