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
- quaintdev 5y agoCost 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.
- antoniuschan99 5y agoHow 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?
