Dear Sir:
We know, we have two sets of devices on our hands.
One is Raspberry Pi and one is Tinker Board 2
Connect a set of Buzzer relay devices to each. Only Tinker Board 2 cannot be used.I have tried other Tinker Board 2s on hand, but none of them can be used.

We went to buy a different relay switch today for testing.
Now it works fine.
