I got a 10” Picade a little while ago, and I’m very happy with it. However, I now want to overclock my Pi 4.
I got hold of a Zalman ZM-NB47J oversized heatsink, but I must move the XHAT away from the Pi to make room for the heatsink.
A male-to-female GPIO 40 pin cable costs more than the Pi on Amazon, so I went with a 40 wire jumper cable set ( see picture please). For now the XHAT is hanging from the Picade, this is just a working setup, I plan to secure it later to the side of the Picade.
The Picade turns on all right, it’s running Lakka, which also works fine. However, I am getting constant low voltage warnings, and the Pi isn’t even over locked yet. I should have seen this coming, those rainbow jumper cables must cause too much of a voltage drop from the XHAT to the Pi.
My PSU is the oficial one (5.1v 3A).
I’d ask, how can I solve this? I thought maybe with a 12v PSU and a 5v power regulator between it and the XHAT?
I’ll be grateful for any recommendations both of setups and what to buy.
