Jamma harness ground connections?

[qjuk]

If you have some heat shrink tubing, you can cut off the hard blue plastic fork connector sleeving and replace it with heat shrink tubing instead. This will make the connector thinner and less bulky so you should be able to fit another fork connector onto the screw terminal.

What I would do however, is have just two fork connectors, with two thick ground wires crimped/soldered to each connector. So instead of having 4 fork connectors with 4 separate wires, just have 4 wires going to 2 connectors. This would then fit onto the GND terminal your pictured PSU, especially if you use heat shrink tubing.

there is also this which i found last night, i could feed multiple ground wires into this and then just have one going to the PSU, that may be my easiest bet

Any pics of the pi2jamma separated from the pi

Both sides close up on the ground solder points and traces .

If you want to post it to me
I’m happy to try it out see if I can sort it .
