#2Great initiative but worrysome execution. Can the team share why we can't buy chips in lots of 100, 1k or even 1M chips? $500k isn't enough for TSMC, so who'll pay them?
The ESP32 seems to have a much, much stronger story.

What your saying about the quantities makes sense but your comparison to ESP32 is strange as that isn't an open core at all.

#4Some pretty concerning red flags: They said "RISC-V", but that's not saying much. Is it RV32I, RV32IM, RV32G, does it have supervisor support, etc. Yes, I know I can look it up on github, but this kind of information should be at the very top of the front page.

#5This is great! The source code is written in Verilog HDL and is located here[0]. I hope they use english instead of spanish as a language to attract more contributors.

I think they are produced on wafers with other things so, presumably a third party is collecting together a load of stuff and having it made together.

RV32IM with interruptions capability. Sure, we will add this at the CS site.

#8Getting 160MHz makes things more expensive, technology wise. Why not starting in a cheaper technology to be open source?

#9Most of dev boards for hobby-end microcontrollers in the market are using high level language to easy the micro programming, is any high level language such as C supported?

#10Hopefully they have something like the modern micros which includes USB interfaces onchip...
