If Seeed send me one, that’d probably solve the problem - the chance of both units being dead on arrival is minimal, but without a third I’ve no way to know which one is the faulty one.
Don’t fancy buying another on spec, though - especially as they’re back-ordered and there’s the cost of shipping on top. And if I got one dead one, there is a chance - no matter how small - of getting another dead one, and I really don’t want to be three in the hole and still not able to get anything working!
