What is the trace thickness or better still, what is the current carrying capacity of the traces?

I’ve hit three continuous amps so far with no problems.

Is it just me, or does the exposed copper between holes on the reverse side make it hard to keep the solder to one hole? Or does this not matter?

There are 5 holes connected together by a copper trace. Note that you will usually insert the component leads through the board from the ElectroCookie label side. A fine tipped soldering iron will help to avoid "Glopping" too much solder. You DO want to avoid bridging, or having solder cross the non-solder areas onto other rows of holes. You might want to try practice soldering a board with pieces of wire- it will teach you some valuable skills in a hurry! Hope this helps!

Great, but why the price increase?

These feel and function great. However, just a few months ago They were available for some €20 less!

Nano fits like a glove

Got these for an illuminated sign driven by a Nano. Seems to be coming together well and this board is ideal for the Nano.
