Controlling up to three chains of 64x64, 32x32, 16x32 or similar RGB LED displays using Raspberry Pi GPIO

Cable that is used in DEC PDP-11 and PDP-8 machines for serial ports.
BC01 is an open-source printed circuit board by anders-bzn, from the anders-bzn/BC01 repository on GitHub. It is a 2-layer board of 53.3 × 55.9 mm with 2 parts on 59 nets, routed with 17 tracks and 9 vias.
This is a little PCB that on a easy way to build a DEC BC01 cable. It has a handle which makes ir easy to install and remove. It has been tested with DKC8-A, KL8E and KL8JA and fits in PDP8/A and PDP8/E.

It measures 53.3 × 55.9 mm and has 2 copper layers, 1.6 mm thick.
2 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 anders-bzn/BC01 repository on GitHub, at the commit this page was made from: the board is BC01.kicad_pcb and its schematic BC01.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 anders-bzn before reusing the design.
