Overview

Controller Module is an open-source printed circuit board by duplow, from the duplow/setup-kvm-3 repository on GitHub, published under the MIT licence. It is a 2-layer board of 99 × 63.5 mm with 38 parts on 59 nets.

It is built around the 74HCT244D, 74AHC1G02GW and 74LS195APC. Its parts include 15 resistors, 14 diodes, 4 ICs, 3 connectors and 2 switches.

Chaveador KVM (Keyboard Video Mouse) para até 3 PCs/aparelhos diferentes conectados simultaneamente, podendo alternar entre sí.

Cada aparelho conectado contará com 3 entradas HDMI, 3 entradas DisplayPort e 1 entrada USB 3.0.

O projeto é montado em cima de um Arduino para fazer o chaveamento entre os aparelhos via teclado, caso opte por um chaveamento apenas via botão fisico o Arduino não será necessário.

O chavemento será feito pelo botão físico no aparelho ou via um teclado USB usando os atalhos:

CTRL+SHIFT+NUM+1 para o aparelho número 1
CTRL+SHIFT+NUM+2 para o aparelho número 2
CTRL+SHIFT+NUM+3 para o aparelho número 3

e assim por diante

Fabricação

espessura minima das trilhas (width): 0.2mm
espaçamento minimo (min clearance): 0.2mm (usado 0.25m)

Módulos

Materiais

Componentes necessários para um KVM de até 3 aparelhos:

Arduino qualquer modelo (opcional)
70x Buffers SN74HC541N (6 por HDMI, 6 por DisplayPort e 2 por USB)
4x Conectores USB 3.0 DIP fêmea
9x Conectores HDMI fêmea link de venda
9x Conectores DisplayPort DIP fêmea
4x Conectores P2 de áudio e microfone link de venda

É possível substituir os buffers SN74HC541N por multiplexadores 74HC4052, porém será necessário muitos deles para fazer o mesmo trabalho, para cada SN74HC541N será necessário mais ou menos 4 multiplexadores 74HC4052.

Questions

How big is the Controller Module PCB?

It measures 99 × 63.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Controller Module use?

38 parts, built around the 74HCT244D, 74AHC1G02GW and 74LS195APC. 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.

Where can I download the Controller Module KiCad files?

From the duplow/setup-kvm-3 repository on GitHub, at the commit this page was made from: the board is projects/Controller Module/Controller Module.kicad_pcb and its schematic projects/Controller Module/Controller Module.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Controller Module design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
