In the Build your own extension of the Extension port documentation (source file), it says
Using a standard RJ-11 connector, it provides power, I2C, and GPIO pins...
(emphasis mine). However, the "Extension Port Pinout" right underneath only shows power (3.3 V and 5 V) and UART pins - no I²C or GPIO.
Which is it then? Either the mention of the I²C and GPIO pins should be removed, or the extension port pins better documented. But it seems there are no pins that could provide I²C/GPIO (there's only one extra pin marked NC), so probably the former.
Please let me know if you want me to open a PR.
