How find my Motherboard main control chip version on ender 3 S1?

I want to flash the firmware to a ender 3 S1. But i don’t know my Motherboard main control chip version. How find it ?

Merci pour votre réponse. I’m french, use simply language.
Thank you!

Hi @BrunoM

As far as I know there is only one variant of motherboard for the Ender 3 S1 and is usually known as hw24s1_301.

You should find all available firmware updates for the S1 here:
Ender-3 S1 Software & Firmware Download

Hope that helps.
