Unclear on Argon GPIO mappings

Hardware
1

Couldn’t find this in any of the official documentation other than “can be used as GPIO” but hopefully someone can point me in the right direction:

Argon pins TX, RX, MI, MO, SCK, SCL, SDA are all documented as being available for use as GPIO but none of the pinouts show their mappings/assignments.

From the PCB layout is it safe to assume SCL = D1 and SDA = D0?
And then SCK = A6, MO = A7, MI = A8?
And where do TX & RX fit?

TIA

If you look under Docs/Datasheet/Argon you will find this:

YES

And then SCK = A6, MO = A7, MI = A8?

YES

And where do TX & RX fit?

Can be referred to either as pin 9 and 10 or TX and RX as in pinMode(TX, OUTPUT);

Thanks for the quick reply! I am familiar with the graphic you referenced. I think a strong argument could be made that additional detail regarding the GPIO naming conventions could be included in this graphic.
