Could one use this to make an open-source cryptocurrency hardware wallet?

I haven't looked into the requirements or the specs on either side so I'm just asking very naively. The $25 price point just seems better than the $100+ for the typical cryptoasset hardware wallet.

I asked the same question here when this went up but I haven't heard anything from anyone. I have a feeling as Bitcoin goes more and more mainstream wallets will get cheaper. It's pretty ridiculous to expect people to pay $50-100 for a single wallet that could easily be lost. Especially when hardware is getting so cheap, there is no excuse for the prices. Either an open source alternative will bring the price down or competition but right now I think the answer to our question is unfortunately, no.
