Description
Kaugummi is a small FPGA-based single-board computer designed to be used standalone or as part of a cyberdeck or wearable computer.
Kaugummi can directly drive an RGB LCD display with a 40-pin FFC connector. It is designed to be powered by Nickel using 6 AA NiMH batteries, with the Blase Dock or the USB-C connector.
See our Zeitreise Cyberdeck for an example of a custom cyberdeck using Kaugummi.
