ESP32-C3 revision engineering sample

[fabianoriccardi]

Hi all,
I was going to buy some ESP32-C3, however it seems that is not easy to find on the market. However, I had found them on mouser.com

https://www.mouser.it/Search/Refine?Keyword=esp32-c3
https://www.mouser.it/ProductDetail/Esp ... Fjq1w70%3D

But all the variants are "engineering sample". What does this mean? Are they good or should I wait a bit more for final silicon?

I hope this is the proper place for this topic.

When I bought the ESP32-C3 DevKitM-1 they make you read a statement on what Engineering Sample means. I clicked through quickly but I think they’re saying not all features are present ( jtag debugging I think and not all specifications are met).
You might not want to do BLE5 range tests for example.

You might want to wait for ESP32-C3-DevKitC-02 which would meet all spesc. But is not in stock until June I think.
