Display hat
About the Display hat
Display hat is an open source PCB design by FOSDEM, published on GitHub. It is a 2-layer board measuring 31 × 65 mm, with 9 components from 7 distinct parts.
By type, the board carries 4 connectors, 2 jumpers, 2 capacitors and 1 resistor.
It belongs with the audio, displays & leds and dev boards & breakouts designs in this gallery.
From the project
A full build needs several parts. All of these should be easily reproducible, while for the ones where we rely on an external manufacturer, we made sure to have ample spares.
A full build needs several parts. All of these should be easily reproducible, while for the ones where we rely on an external manufacturer, we made sure to have ample spares.
You will need one of each item, except when stated otherwise.
The case is an off-the-shelf widely available 1U case, made by Gainta.
We only use the actual enclosure. All other bits can be discarded.
