The Penkesu is the perfect DIY computer for anyone who wants a retro-style laptop with all the power of a mighty [Raspberry Pi Zero 2 W](/products/raspberry-pi-zero-2-w/). The compact physical dimensions and ortholinear keyboard make it perfect for taking on the go, and the Waveshare 7.9-inch capacitive touchscreen display provides a clear and vibrant picture in most conditions. The case of Penkesu Computer is designed around the display and keyboard to achieve a relatively compact physical dimension. The display is a Waveshare 7.9-inch capacitive touchscreen, 400 x 1280 resolution, connected via a ribbon cable adapter to the Zero 2 W’s mini HDMI output. The rest of the parts are bespoke [3D printed](/products/categories/3d-printers/) or off-the-shelf products, to better accommodate the 48-key low profile keyboard that connects via an Arduino Pro Micro that feeds its signals to the Pi’s second micro-USB port. The switches are Kailh Low Profile Choc V1 models, with Choc low-profile keycaps on top. As is common with 48-key keyboards, there are additional modifier keys that allow a large number of functions to be performed. Inside, you’ll find a 3.7V Li-Po battery pack hooked up to an Adafruit Powerboost 1000C to act as a load-sharing charge controller and to feed power to the Pi, keyboard, and screen. The Penkesu is also [open-source](https://github.com/penk/penkesu), so you can customize it to your own needs.
