This 1.25 mm pitch 4-pin cable is a compact, Molex PicoBlade-compatible connector cable for projects where standard 0.1″ headers are too bulky. At 20 cm long, it provides a convenient connection length for internal wiring without excess slack.
The friction-lock connectors provide a secure, click-in connection that is easy to mate and unmate. This cable uses 1:N wiring, meaning pin 1 on one connector maps to pin 4 on the other side (reversed order).
Key Features
- 1.25 mm Pitch – Ultra-slim alternative to 0.1″ and JST PH connectors
- Molex PicoBlade Compatible – Works with standard PicoBlade headers
- 4-Pin Configuration – Suitable for I2C, sensor, and peripheral connections
- 20 cm Length – Practical for internal board-to-board wiring
- Friction Lock – Secure, click-in connection

Jargon buster
Plain-language definitions for the technical terms used above.
- Headers
- Rows of metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- JST PH
- A small keyed plug-and-socket connector with 2 mm pin spacing, often used for low-power electronics connections. You need the correct JST PH cable, and its current rating limits how much power should be passed through it.
- pH
- A measure of how acidic or alkaline a liquid is, on a scale where 7 is neutral. For a water monitoring kit, pH tells you about water chemistry and whether the included probe matches the range and accuracy your project needs.
