Hi,

Did you compare the pin outputs? Is there a mismatch?

Hi Ensar
Compare with what?
I havent changed any pin settings. Just installed the os Tinker Board S Debian 10 v3.0.23.

Is the Tinkerboard GPIO the exact same as a Raspberry Pi GPIO?
Pin for pin compatible?

5

Can you check if the GPIO26 pin is set to LOW?

I will check and reply to you, thanks.

Hi ScottV
honestly I don’t know if they are same cause I won’t use the GPIO pins for my project
