Greaseweazle is an open-source printed circuit board by tebl, from the tebl/Amiga-DrawBridge repository on GitHub. It is a 2-layer board of 90 × 94 mm with 26 parts on 28 nets, routed with 290 tracks and 36 vias.
Its parts include 9 resistors, 6 connectors, 2 diodes and 1 transistor. It belongs with the retro computing and games boards and the STM32 boards of this library.
A faceplate designed to be installed onto the main Greaseweazle-module, it has cutouts for the 34-pin and 26-pin IDC sockets as well as the LEDs found on the module. For a version that does not include the 26-pin Amstrad-centric connector, see Greaseweazle FA1 instead.
Note that as the faceplate will sit a bit higher up on the standoffs, the LEDs will need to be soldered around a millimeter above the board - the recommended way of installing them is to insert them into the footprint (longer pin in the round hole), install the faceplate and then solder the LEDs into place with the LED flush against the faceplate.

26 parts. 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 tebl/Amiga-DrawBridge repository on GitHub, at the commit this page was made from: the board is Greaseweazle/Greaseweazle.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask tebl before reusing the design.
