### GPIO usage - important change
!!! important
This can be confusing at first, so make sure to read this part carefully to understand it.
Since v1.0.0, GPIOs are no longer meant to be referenced by `D#` numbers.
Input/output pin numbers in Arduino code (i.e. `digitalWrite()`) use Arduino pin numbers - for example `D1`, `D3`. This is the same as simply `1` or `3`, but it cannot be confused with CPU GPIO numbers.
On the board pinout page, the purple blocks represent Arduino pins, while the dark red blocks refer to GPIO numbers.
If your program is using Arduino I/O functions, refer to the [Migration guide](../dev/migration_v1.0.0.md) to modify your program accordingly.
