Description
Wolfsfeld is an ultra-low-power stand-alone 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).
Planned gateware:
- Hypervisor SOC/OS with a real-time debugger, assembler, disassembler, hex/code editor, Zwölf host controller and serial terminal.
- At least one Zwölf CPU instance
Currently available for reservation. Final appearance, specifications, pricing and features subject to change.
