Vcc is 3.3v or 2.8v
vccq is 1.8v
Is correct

You swapped VCC and VCCQ.

on the above picture on jtag pinout it does not state vccq which pin is vccq ?
1 = vcc

= vccq?

can tell me please , thanks

[Legija]

On JTAG port Vcc pin is sensor input, not supply. It just serves as sensor to detect I/O level on target.

[kammy6000]

ok i noted this that vcc is sensor



but which pin number is vccq on jtag? which number please 1-20 thats what need to know , is vccq external supply , i need connect 5 wires i onlyt have vccq missing



thanks

[Legija]

There is no VCCQ on JTAG.


You need to read and learn some basics first.

[kammy6000]

so this what i am trying to do but i just need to know which pin to connect to vccq as mentioned in pic , i am also reading guides but there is no clear answer to my problem , thanks

[Legija]

Vccio = vccq

VCCQ on Riff Box v1

Hi,
in the image below I put an arrow where you have the VCCQ.
You have to scratch the track a bit until the copper comes out and solder a wire that will then have to come out of the box: this is the VCCQ pin.

Best regards and good working in progress.
