Overview
Input is an open-source printed circuit board by phooky, from the phooky/Flat-SIP repository on GitHub. It is a 2-layer board of 65 × 45 mm with 48 parts on 33 nets, routed with 250 tracks and 28 vias.
It is built around the LM6172IM, LM1881 and CD4053BE, with the MMBT3904 among its other parts. Its parts include 16 capacitors, 15 resistors, 4 ICs, 2 diodes and 1 transistor.

README
README.mdAn attempt at a flat version of the Sandin Image Processor.
Rough plan:
- Start with input/sync strip and NTSC encoder modules. If we can get those working, the rest is simple.
- Full-size PCB behind Al panels.
- Find original panel size. (4U?)

Questions
How big is the Input PCB?
It measures 65 × 45 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Input use?
48 parts, built around the LM6172IM, LM1881, CD4053BE and MMBT3904. 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 Input KiCad files?
From the phooky/Flat-SIP repository on GitHub, at the commit this page was made from: the board is modules/Input/Input.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Input design in my own project?
Its repository states no licence, so its author keeps all rights: ask phooky before reusing the design.
