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
