portapack-mayhem/mayhem-firmware
The firmware for the HackRF+PortaPack H1/H2/H4/H4M

This is a slice extender panel, which contains a small cpld, aimed to have configurable the bridge between the slot and the slice panel.
Xmos cpld is an open-source printed circuit board by bfarago, from the bfarago/xmos_cpld_slice repository on GitHub, published under the LGPL-3.0 licence. It is a 2-layer board of 48 × 24.8 mm with 15 parts on 90 nets, routed with 1,300 tracks and 147 vias.
It is built around the 5M40ZE64C5N and NCP699SN18. Its parts include 5 capacitors, 2 ICs, 2 connectors and 2 switches. It belongs with the fPGA and programmable logic boards and the FPGA and CPLD boards of this library.

It measures 48 × 24.8 mm and has 2 copper layers, 1.6 mm thick.
15 parts, built around the 5M40ZE64C5N and NCP699SN18. 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.
From the bfarago/xmos_cpld_slice repository on GitHub, at the commit this page was made from: the board is kicad/xmos_cpld.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the LGPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
