While the specs are impressive a lot of questions a rise :
- Support – Espressif is a small company as far as we knew – would they be able to support both chips in the long term?
- Compatibility with esp8266? – The new ESP32 will use the RTOS based SDK and most APIs are said to be compatible with the esp8266 SDK.
- Price – The price will be higher than esp8266 but not much higher.
Beta testing program is coming soon.
