How to determine ROCK 4C+ version (v1.0/1.1/1.2)?

The documentation of the GPIO for the Rock 4C+ makes some distinctions between versions of the board:
https://wiki.radxa.com/Rockpi4/hardware/gpio

There are two versions of the pin diagram:

  • v1.2: general purpose input-output (GPIO) connector
  • v1.0/1.1: ROCK 4C+ v1.0/1.1** general purpose input-output (GPIO) connector if you click the Expand button.

It is stated that:

ROCK 4C+ v1.0/1.1 are pre-production version. Mass production began from v1.2.

How can I tell if I’m running a board version v1.0/1.1 or v1.2?

Thanks in advance

you can see the version from the Silkscreen on board ,such as “ROCK 4C PLUS V1.41” , V1.41 is the version

Thanks for the info!
