Controllertht is an open-source printed circuit board by espcaa, from the espcaa/colloseum-controller repository on GitHub. It is a 2-layer board of 125.8 × 46.8 mm with 14 parts on 21 nets, routed with 189 tracks and 23 vias.
It is built around the CH552G, 204-10SUBC/S400-A4 and YF16-FL7.2-B5KA(45-10)-R-A28. Its parts include 6 resistors, 4 ICs and 4 diodes. It belongs with the 8051 (CH55x, STC, AT89) boards of this library.

Based of an CH552G it can act as a usb keyboard so that your pc recognize it as a keyboard without any specific driver! It uses quite a few techniques to bring down cost, everything is tht, the usb port is just a trace on the pcb, making it around 2-4$/board (hopefully)
(prices for 1 unit, at 50 costs will go -50% thanks to lcsc)

You also need some pla/petg/whatever to 3d print the case The pcb can seem expensive but that's just the ENIG setup fee, we're at less than a dollar per pcb when ordering 50

It measures 125.8 × 46.8 mm and has 2 copper layers, 1.6 mm thick.
14 parts, built around the CH552G, 204-10SUBC/S400-A4 and YF16-FL7.2-B5KA(45-10)-R-A28. 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 espcaa/colloseum-controller repository on GitHub, at the commit this page was made from: the board is kicad/controllertht.kicad_pcb and its schematic kicad/controllertht.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 espcaa before reusing the design.
