KlusterLab is an open FPGA development platform designed for experimenting with high-speed interfaces and formally verified IP cores.
It measures 91.9 × 91.9 mm and has 2 copper layers, 1.6 mm thick.
29 parts, built around the 74LVC1G07SE-7-MS, RC0603FR-071KL, LTST-S270KGKT and LTST-S270KRKT. 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 IdoAzulai/Rocket-Boards-Uni-Project repository on GitHub, at the commit this page was made from: the board is hardware/rpi-cm4-base-carrier-rocket/rpi-cm4-base-carrier-rocket.kicad_pcb and its schematic hardware/rpi-cm4-base-carrier-rocket/cm4-gpio.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask IdoAzulai before reusing the design.
