S3 or C5 for futureproof? #99
-
|
I am building a custom pcb for smart thermostat. I have about 8 in my house so that would make it the perfect fit to build an Array. I am currently using S3 due to microwakeword requiring psram. I've seen from the roadmap here that C5 has been the goto target for multi-array 3d spatial. Do you think we would be able to have it work for S3 in the future? Side question: I love using gh discussions but is there a discord or matrix where more generic/instant chat related to this project can happen? |

My bad, I assumed the question was asked in the MicroPython Repo Sorry for the confusion |

Great question @vekexasia , and thanks for bringing this up. The roadmap is a moving target: it reflects my current direction, but it evolves with experimentation and community feedback. Suggestions like yours are very welcome and genuinely useful. Right now, C5 is mainly interesting because of 5 GHz support. That is the key reason it appears in the multi-array / 3D localization direction: moving from 2.4 GHz to 5 GHz roughly halves the wavelength, so in practice you can reduce antenna spacing by about 2x for comparable array geometry. That said, this does not mean S3 is a dead end. There are promising projects showing wireless phase coherence on other ESP32 families (for example ESP-PPB from @jonathanmuller, which uses ESP32-C3), so in principle an S3-based path can still be viable depending on architecture and constraints. So short answer: C5 is currently attractive mostly for 5 GHz physics/array density, but the roadmap is not fixed, and S3-focused contributions or experiments are definitely welcome. |

On the Discord question: there isn’t an official ESPectre Discord yet. I’m open to creating one if more users ask for it. If a couple of community members would like to help with moderation/management, I’d gladly set it up and give it a try! |
