Pi-top CEED - 40-pin connector vs jumper cables

So some CEEDs are coming with a full 40 pin connection to the hub board and some are coming with three individual jumper cables that only connect six of the forty pins. Why do these two versions exist and why do they seem to be given out at random?


I believe all CEEDs should come with the 40 pin connector. CEEDs with the jumpers CANNOT use the Pi-Top Proto board. 


Worse though is the fact that the connectors on the jumpers are too long causing the wires to be in the way of closing the acrylic slice/cover. It can be closed but you can feel the friction of the wires against the cover. This seems like a serious design flaw. Repeatedly opening and closing the cover to get access to the GPIO pins is going to stress those wires to the breaking point.


The 40 pin connector does not interfere with the cover and gives you full access to the GPIO as long as you have a Proto board.


For those of us who got the jumper cable version, please make the 40 pin connector available.

The hardware installation instructions are inside the cover of the pi-top speaker package. You need to tear it open to see them. Set the switch to (m) for mono, (l) for left or (r) for right.
I am trying to connect a set of pi-top speakers in my CEED. I have the 40 pin connector cable version, and it is connected to my RPI3 to power the RPI3. Do I connect this 40 pin connector instead to a pi-top speaker, then power the RPI3 by a short USB cable from the CEED power supply board to the RPI3? Sure wish this was explained somewhere........ :{}

I got one with the three cables and also experience them as too tall and the frustration that they are zero documented and I have no idea what they are for, except that if I start the pi-topCEED without them on alls seems to work just fine (as long as I power it).

I doubly found it painful that the one three pin connector has three black cables providing no orientation and a near invisible arrow I did not see at all and hence took a punt and put it on the wrong way, before using a torch, finding the arrow and putting it on the right way. No idea of of the consequences of running it with those three flipped and support has not answered me that!

I would love to see some documentation on the pi-top Hub, what it is, what it does, what all its pins are for and what exactly the three connectors to the Pi 3 are for!

Excellent! I look forward to hearing what you've got going, Jarle.

Power on/off works flawlessly with USB from display board - not to bothered aboyt the display brightness at the moment as keeping the lid closed / open at will without snagging GPIO Cables is more important to me now. I have had a look at GPIO pin attachments and see a neat hack coming on - I'll keep you posted :P


You can use the 5V and Ground connection from the hub to the rpi either with the jumper cables (or the 40 pin cable) or with the usb connection or both at the same time. In any case the power to the pt is cut off if you turn the hub off. To use the brightness adjustment, the 3 spi pins need to be connected! There is no way to do this through usb. In any case you need to make sure that the rpi is going through the proper shutdown process before the power is cut. Otherwise you will sooner or later loose data on your SD card!

Power on / shutdown works when removing the 5v and Ground jumper cables and using the USB connection from the hub board to the Pi instead.

Hmmm - can the brightness / shutdown be rerouted or made functional for USB with a software update ?? (Yes I know n00b question) :P


On a CEED with the 40-pin cable, I wonder if you can do this powering of the Pi via the USB port.

The brightness adjustments and the shutdown use spi. If you do not connect spi between hub and rpi this will not work.

I will come back to you on that on will test later - definitely turns on !!

Jarle, does the hub board still control the power to the Pi that way, turning it off on shutdown?

Just switched from GPIO power to USB POWER - works great !! What you need is a short USB cable that has got a 'short head ' preferably noodle style to plug in to controller board and hook it up to your Pi (see pic)

My pi-topCEED was delivered with 3 individual jumper cables instead the 40 pin GPIO connector cable, too. I need the 40 pin cable to able to use a pi-topPROTO board. How can I receive a 40 pin GPIO to hub board connector now? 

Yes the 'GPIO LEADS' slightly to tall - Acrylic Sliding Lid does therefore not close easily - could the Pi NOT be powered by USB on the 'logic board' ?? Looks like a rushed engineering solution really !!
