Description
Wolfsfeld is an ultra-low-power stand-alone open-source handheld FPGA computer intended for educational purposes and survival computing.
Wolfsfeld is literally field programmable. Programs can be entered manually (or uploaded) into non-volatile F-RAM where they can be tested and then transferred onto separate Zwölf modules.
Wolfsfeld requires one AA battery (not included) of either 1.2V (NiMH) or 1.5V (alkaline).
The official firmware is still under development and Wolfsfeld is currently only recommended for FPGA developers who want to assist with the official firmware or implement a custom system.
Wolfsfeld is now available on backorder. These orders are built on-demand and ship within 3 months (usually sooner). You can optionally specify custom case colors in the order notes. The default case color is olive green.
