Development platforms, microcontrollers, ICs and standard interfaces
PCIe 6-Pin GPU Power Connector
6-pin auxiliary power connector defined by the PCI Express Power Supply Specification, supplying up to 75W (3x +12V, 3x GND) to graphics cards in addition to the PCIe slot's own 75W.
PS/2 (Mini-DIN 6) Keyboard/Mouse Connector
6-pin Mini-DIN connector introduced with the IBM PS/2 for keyboard and mouse interfaces. Uses synchronous serial protocol with clock and data lines. Purple = keyboard, green = mouse.
Parallel Port (DB-25 / LPT Interface)
Standard 25-pin D-Sub parallel interface for printers and peripherals. Pin 1 is Strobe, pins 2–9 are bidirectional 8-bit data lines (SPP/EPP/ECP modes), pins 10–13 and 15 are status inputs, pins 14/16/17 are control outputs, and pins 18–25 are signal ground.
RCA (Phono) Composite Connector
Single-conductor friction-fit coaxial connector, colour-coded yellow for composite video or red/white for stereo analog audio, ubiquitous on consumer AV equipment.
RJ11 6P4C Modular Connector (Telephone)
6-position 4-contact modular connector used for analog telephone lines, DSL connections, and fax machines. Smaller than RJ45 with 6mm width.
XLR-3 Balanced Audio Connector
3-pin professional balanced audio connector for microphones, mixer inputs/outputs, and DMX512 stage lighting control. Provides shielded differential signaling for noise rejection.
XT60 DC Power Connector
High-current 2-pin DC power connector rated for 60A continuous (30A per contact). Standard in RC hobby, drone, e-bike, and 3D printer applications. Gold-plated bullet contacts with polarized housing.
Frequently Asked Questions & Transparency
Helpful information about data sources, usage, and privacy
Where does the pinout data and technical specification come from?
The pinout data and technical specifications are based on official manufacturer datasheets as well as publicly available documentation and community resources. As PinoutDatabase is an independent project maintained by me as an individual, I strive for high accuracy, though inadvertent mistakes can still happen.
Can I use the graphics and how are they created?
The SVG vector files and PNG graphics are free to download and use for private/personal purposes. Depending on the component, the diagrams are either crafted manually or generated automatically based on package footprint and pin definitions.
Found an error or missing a component? How can I give feedback?
Community feedback is always appreciated! If you spot an error or are missing a specific component, please use the 'Report Issue' button directly on that component's page or send me a message via the contact form.
Is the site free to use and how is privacy handled?
Currently, using PinoutDatabase is completely free and requires no registration. All interactive web tools run entirely client-side inside your browser. Detailed information regarding data processing can be found directly on our Privacy Policy page.
