Awesome. I wonder if, in future, ESP8266 chips will be replaced with this one since former is WiFi only. There really needs to exist an alternative WiFi chip from another manufacturer. It would significantly drive the price down due to competition. Currently there's no competition to Espressif in this segment. Maybe Raspberry Pi should come up with RP2040 WiFi chip. That would be amazing. While we are on this topic I did a lockdown project based on ESP8266 thought I had share :p https://www.ankshilp.com/monitoring_solar_panel_output_over_wifi/ https://www.ankshilp.com/monitoring_solar_panel_output_over_...

  Not available at all in India. Also, other international vendors don't seem to have it too.

Esp32-S2 are pretty much the 8266 replacement chips. ESP8266 don't have secure boot or flash encryption so it's not good for production. C3 doesn't have Risc-V ULP, whereas the S2 does, but the S2 doesn't have BLE! I'm waiting for a RISC-V ESP with ULP and an actual low power consumption BLE. Espressif also announced the ESP32-WROOM-DA which is has dual antenna configuration, can't wait to see how it handles! Very cool project, I want to play with Solar Panels as well it looks very fun :). Please check out my project too :P https://www.kokonaut.com https://www.kokonaut.com

  Cost of ESP32-S2 is 5 times that of 8266 at least in India. From price perspective C3 looks like replacement for 8266. BTW cool project.

    How is the price comparison with just ESP32? The S2 is more of a direct upgrade as it has ULP and only wifi. Surprising the c3 is that much cheaper, the release is also much more recent. Wonder why that's the case?
