Overview
MiniDIN9 Breakout is an open-source printed circuit board by zaxour, from the zaxour/9Pin_BreakoutEx repository on GitHub. It is a 2-layer board of 21.6 × 22.2 mm with 15 parts on 11 nets, routed with 72 tracks and 9 vias.
Its parts include 11 connectors, 2 resistors and 1 capacitor. It belongs with the interfaces and adapters boards of this library.
README
README.md9Pin_BreakoutEx
Breakout board for 9 pin mini DIN connectors with additional features for audio and sync.
Leaving the jumpers un-bridged and components empty means the board will act like a standard 9 pin breakout DIN.
If attaching to a system that doesn't have composite and only has a 5V TTL level sync, use the following BOM:
C1: 220uF 6.3V Tantalum 3528 size capacitor R1: 620 Ohm 1/8W 0603 size Resistor R2: 86.6 Ohm 1/8 0603 size Resistor
RGB mods for older consoles tend to make the user decide between Composite Video level sync or TTL sync. With this breakout, simply install the resistors and capacitor (value indicated on bottom silkscreen) and use the TTL sync from the RGB modification. This will simultaneously deliver a proper sync voltage to the Composite Video pin on the DIN for using HD Retrovision cables. ***ENSURE THE RGB MOD CAN DRIVE TWO 75 OHM LOADS (Such as THS7374, THS7314 or similar) ***
The solder jumper for audio can be used as follows: -Right: Connects Right and Left audio nodes, passes to both pins. -Left: Connects Right audio to the Mono pin
Both jumpers can be soldered to make sure a mono audio signal goes to all of the audio pins.

Questions
How big is the MiniDIN9 Breakout PCB?
It measures 21.6 × 22.2 mm and has 2 copper layers, 0.81 mm thick.
What parts does the MiniDIN9 Breakout use?
15 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.
Where can I download the MiniDIN9 Breakout KiCad files?
From the zaxour/9Pin_BreakoutEx repository on GitHub, at the commit this page was made from: the board is MiniDIN9 Breakout.kicad_pcb and its schematic MiniDIN9 Breakout.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MiniDIN9 Breakout design in my own project?
Its repository states no licence, so its author keeps all rights: ask zaxour before reusing the design.
