Can't recall if this was discussed before, but after I started playing with TX/RX again the other day I noticed that the print screen on the boards says G, Ref D1, D0, but the pinout diagram says G, Ref, D0, D1

And if D0 is wrong in the pinout diagram is TX/RX wrong as well?

Hi Xnih13,

Thanks for pointing that out.

The board pin-out is the wrong part. The TX and RX positions are fine, but the D0 and D1 are inverted.

The correct sequence is:
GND
VREF
D1 (TX)
D0 (RX)
A7
A6
...

I'll make sure we have the board pin-out diagram fixed.

Thank you again for pointing that out.

Regards
