The HackberryPi_CM5 project is a RaspberryPi Compute Module SBC(single board computer) powered handheld computer with reuse of original keyboard from old Blackberry phones. The goal of the project is to create a portable linux-powered computer that lets the user gain a deeper understanding of Linux and explore the architecture of hardware, software, and the Linux kernel. This repository will be used to share information about the project and tutorial about how to make use of this device.
Designer's bio: Zitao, currently a master’s student in Mechanical Engineering and Industrial Design at the Technical University of Dresden, Germany
Overall dimensions: 143.5x91.8x17.6mm
Weight: 306 Gramm(with battery,cm5 and heat sink)
Upper and lower case made of aluminium
Middle part 3d printed

In this page you can find the 3D model of each part of this device, you can print or modify the part yourself.
The HackberryPi_CM5 comes without the CM5 unit. Generally, you only need to install the CM5 and the passive heatsink on top. For details, please refer to this page.
This page offers an in-depth hardware overview of the HackberryPi_CM5, designed to guide anyone interested in creating an adapter board for the CM5 module, exploring the keyboard’s hardware architecture, and related concepts. For more details, please visit this page.
There are dual speakers on board, it is needed to pair with the bluetooth audio module to make sound for more information please refer to this page.
Because of the metall case and the mounted heat sink, the performance of the original PCB antenna might be a little bit disappointing. This page can tell you how to assemble an external antenna;
