Using the GPIO and HDMI Connector with the AutoPi casing

This is a step-by-step guide on how to access the HDMI on your dongle.

This guide does require that you have a little bit of DIY abilities/skills, but you can still manage it even if you are not DIY savvy.

  1. First, you need to make sure you have the following; your dongle separated, a knife, and a lighter.

  1. The first step is you need a sharp knife, we recommend a hobby/pocket knife; then use the lighter.

  2. Place the knife above the flame and slowly heat up the knife, so it can cut through the device easier.

  3. Once you have the dongle separated, inside the top casing, you’ll be able to see the subtle markings of where to cut.

  1. On the broad side of the top casing, there is this subtle square indent, and here is where you should cut if you want to access the mini HDMI port.

  1. For the GPIO pins, there is a rectangular cutout marking on the top casing. This is where you should cut if you want to use it for the GPIO pins.

  2. Remember to be methodical, careful and slow when cutting in order not to hurt yourself or do damage to the device.

  3. Congratulations, you can now access both the GPIO pins, and the mini HDMI port.


surprised the only way to access them is to hack away at the case.

In the future maybe a revised case design could have removable covers that click into place to cover the ports if they’re not used?

Hi Andy

The reason we chose the current design, is due to a range of factors. With price of course being a factor, and combine that with the fact that we expect most users to not use the connectors, we had a hard time to justify the increase in price for such a design change. As that would increase the complexity quite a bit, we chose the middle ground, by having the decreased thickness that allows for easier removal of the cutouts.

Also, the users who utilize those connectors may also use the RPI3 adapter, where the case is not compatible, so that further lowers the number of people who has to modify the case to access the connectors.

We will consider it for a future iteration though.

Best regards
