Arduino nano BLE - A0-A7 pins - can I use tham as digital output?

I suffer from lack of digital pins, Can I use somehow A0-A7 pins as digital outputs?

Yes, you can, they are numbered like this

A0 is 14
A1 is 15
A2 is 16
A3 is 17
A4 is 18
A5 is 19
A6 is 20
A7 is 21

Use them as you would any other digital pin

A4 and A5 have pullup resistors on them for use with I2c so probably best not to use them

@Micromouse-me-uk , thanks. It is working. Also A0-A7 can be used not only the numbers.
