A 3.5 mm (1/8") 4-pole TRRS audio plug with screw terminal connections — no soldering required. Use stranded or solid-core wire and a small screwdriver to create custom audio cables, breakouts, and test leads.
TRRS stands for Tip, Ring, Ring, Sleeve, providing four contacts: three signal lines and one ground. This connector type is commonly used in smartphones and headsets for stereo audio plus a microphone channel. On a Raspberry Pi, the extra contact carries composite video. The terminal block is labelled GND–Ring–Right–Left (Sleeve–Ring–Ring–Tip order). May come with nickel or gold-plated contacts.

Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- Terminal block
- A connector used to join wires together in a neat, removable, or serviceable way. For this product, it helps split one power input into several outputs without soldering.
