These are development, beta boards. They are not finished product.
Finished, cased, tested (CE,UL, RF) product with polished software and manuals come later next year.
That said, we are pretty sure they mostly work, but we have not had time to test fully or for a long time.
They are therefore dont have the normal warranty requirements. You are joining in the development, in return for early access.
Of course we will be sympathetic to boards that are dead on arrival and the like, but we have no formal scheme in place yet.
Calling them development boards does not negate the laws of any country. You are selling to the public not a business to business sale. These statements do not reflect well on the Foundation. The EU distance selling regulations apply as will the UK Sale of Goods Act and equivelant in other countries. If there is a EU or UK act that negates the protection those acts/directives grant, please state it.
