This sounds very memory/storage constrained. A Raspberry Pi is cheaper and far more powerful. Surely there should be some way to improve?
Good points. It has sufficient to store private keys and generate signatures. That's the important part.
The rest of Wallet management can be done on the PC side.
The main advantage over the rasberry Pi is a final product will be easy to pack with you. Like a thumb drive.
The price is high. I agree with you. Wish I had the resources and help to make a final mass produced product.
Low volume engineering is more costly
If we get through the first stage of development, at least we will not need the PK3 programmers because of a boot loader.
Maybe by then, i will learn of quicker and cheaper ways to purchase PCBs and assembly methods.
Should be able to get this in the $20 dollar price range, but that's not realistic in the short term.
I will be preparing the order for the PCBs and components this weak so I will be able to refine the price.
The first lot of PCBs is for hardware validation so it will be a low volume order (around 5 maybe).
Anyone can point me to a good PCB fab house would be appreciated. I need at least 6 mils trace to trace.
