Shorter display cable

I received the Touch Display and keyboard today. Really excited to start thinking about projects to use them in. I’m impressed with the easy setup and build quality of the accessoires.

However. I’m a bit confused by the display cable setup. There is a mount for the pi-top[4] on the kickstand of the display suggesting that you mount the pi-top[4] here when using the screen.

However all the pictures on the website show the pi-top[4] lying beside the screen+keyboard connected with the (teal coloured) display cable. The 2 connectors are very close together when the pi-top[4] is mounted so ideally there would be a shorter cable to connect these.

Are there plans to release a shorter (and more flexible) display cable for use with the display?

This looks very clunky:

Hi @jwktje, yeah we discussed this a lot - we decided that the longer cable made more sense because using pi-top [4] with project kits (Foundation Kit or Robotics Kit) was how most people tended to use the screen anyway.

With my own set up I have my robot ([4] + Expansion Plate + Robotics Kit) plugged into a pi-top display and the long cable coupled with the screen being powered by pi-top’s battery is really convenient - especially when I’m doing OpenCV stuff and need to move it around occasionally for testing.

Anyway, back to your suggestion: there are two options:

  1. A shorter cable

  2. A small dual-ended adapter with two male Type-C plugs coming off it - this would essentially lock the [4] in place when it was placed on but would be the tidiest solution if you wanted a laptop or tablet configuration

Which option would you prefer?

I really like the idea of the dual-ended adaptor, although I do realise it would be more expensive to produce due to the moulding.

A (very) short cable would be acceptable, but less robust and could still be accidentally pulled out if caught on something.


Both options would be neat but I also really like the idea of an adapter. Maybe it could just be as simple as a PCB with 2 angled USB-C plugs that are aligned correctly, saving the need for injection moulding. Like how some Raspberry Pi third party displays connect to the HDMI.
Not exactly like this but kinda like this:


@GeekyTim & @jwktje a Shunt (dual-ended adapter) like you suggest would be a neat way to connect the Pi-Top[4] and display when you want to move it around like a laptop without the risk of snagging.

The Long Display Cable is great for using with a full size desk HDMI monitor or connecting to a PC and allowing people to fiddle with the PiTop[4]. But when used with the PiTop[4] on your desk to left of the Touch Display it is too long and gets in the way. A medium sized (40cm) display cable would be better for this use case. Interestingly the existing cable is the right length to use the PiTop[4] on the right.

So duwudi I’d request that you offer both a Shunt and a Medium Display Cable. The OTG functionality enables easy switching of cables without switching off.

While we are discussing cables, would you also be able to offer the cables needed to hook up other Raspberry Pi computers to the Display Adapter. I’ll post a separate topic about needing instructions for the Display Adapter and the need for the ports to labelled on it.

@duwudi the cables to hook up other R-Pi’s to the Display Adapter would also need to be fairly short, like the ones in the photo on the website.

A shunt would be great for my use-case. The current display cable serves me fine in any situation where I don’t have the pi-top[4] docked.
