After installing the ribbon cable for the Pluto HDMI mod I was sceptical and double checked both Helder’s website and the Picoboot Github as to what was needed.
Let’s get the moaning out the way first.
1. Helder’s website had a big warning about this ribbon cable missing something for a future Picoboot FW update to get IGR working, not sure I’m too bothered about this… plus Helder said it should be an easy fix adding just 1 wire. Haven’t looked into that further as the FW doesn’t exist yet anyway.
2. Then there’s the fact I can’t use the 3D printed holder I purchased with it as the ribbon cable is designed to place the Pi the other way around. I really don’t want to stick it to the fan but it look like I’ll have to.
Both points not raised by ZedLabz in the product information and they even suggest them as products often bought together??
Then there’s the good points which outweigh the above. The ribbon cable does have the protection diod built in. When reading the installation guide on GitHub it was saying about not wanting 5v to get shorted into any of the 3.3v data lines as it could cause damage but this diod only protects against reverse voltage not over voltage? Maybe I’ve missed something but at least it’s there as recommended.
The main thing I’m sold on is being able to run the ribbon under the shielding so I’m not hacking any more holes out of it for the cables.
As a side note, even after warming the heat sink up, getting it off with all the thermal pads in tack is near impossible so I recommend getting a set, ZedLabz didn’t have them in stock at the time so I got a set of sheet to cut my own elsewhere. 1mm, 1.5mm and 2.0mm are needed.
Overall, I’m happy.
