From the paranoid tinfoil hat wearing department, be careful where you buy some of these boards from.
Not necessarily anything malicious directed towards Bitcoin wallets, but even at the ridiculously low price points that you could find and online there are still a ton of counterfeits out there.
I'm assuming that they are just cheap knockoffs being passed off as the less cheap real thing. But in the end you don't have a verifiable source of where some of these chips came from or even who did what at the factory when they were assembled.
Why anyone would create a pirate / clone M5 stack is beyond me, but I they are out there
