That's exactly what's needed. The pi zero platform is much too much overhead. Brilliant idea to port it to a microcontroller 💯🙏

The hope is that the RP2350 microcontroller will be an easier platform on which to port SeedSigner to MicroPython. Getting us onto a microcontroller (while still fully supporting the original Pi Zero hardware/codebase, of course!) will open up some huge new possibilities.

It's amazing that nostr:nprofile1qyt8wumn8ghj7etyv4hzumn0wd68ytnvv9hxgtcpz9mhxue69uhkummnw3ezuamfdejj7qgcwaehxw309anxjmr5v4ezumn0wd68ytnhd9hx2tcprpmhxue69uhkxetvd3shytnwdaehgu3wwa5kuef0qy88wumn8ghj7mn0wvhxcmmv9uqzqxj6lwv69s9n5z9y52h0c9r2ec8fuak2pe9nuarj6dy3eqp4hta3ks7myh and "DT" and others were able to create a custom Linux OS for us (with reproducible builds!!! 🤯) that gets SeedSigner booted up and running in ~12secs.
BUT, yes, a full linux OS is a ton of overhead. Running bare metal on a microcontroller with basically instant-on and hopefully good enough performance (Pi Zero cpu is a BEAST compared to any microcontroller) will be amazing.
