This repository contains the hardware design files for the BeagleWire.
The BeagleWire is an FPGA development platform that has been designed for use with BeagleBone boards. BeagleWire is a cape on which there is FPGA device - Lattice iCE40HX. The Lattice iCE40 is a family of FPGAs with a minimalistic architecture and very regular structure, designed for low-cost, high-volume consumer and system applications. The significance of FPGAs is continuously increasing, as they are more and more often used for supporting work of ARM processors. BeagleWire does not require external tools (JTAG) and the whole software stack is Open Source. iCE40 is an energy saving device, allowing to work with small batteries. FPGA cape allows easy and low cost start for beginners who would like to take their first steps in working with FPGAs. The BeagleWire creates a powerful and versatile digital cape for users to create their imaginative digital designs.

Questions
How big is the Beagle wire PCB?
It measures 68.5 × 89.9 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Beagle wire use?
104 parts, built around the M25PX32-VMW6E, AT24CS32-XHM-B, MCP1826S-1202E/DB and MCP1826S-3302E/DB. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Beagle wire KiCad files?
From the mwelling/beagle-wire repository on GitHub, at the commit this page was made from: the board is beagle-wire.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Beagle wire design in my own project?
Its repository states no licence, so its author keeps all rights: ask mwelling before reusing the design.
