A slim, reliable 1.25mm pitch cable with 6-pin connectors on both ends and a 20 cm length. The friction-lock connectors provide a secure, satisfying click for lightweight connectivity where standard 0.1" headers or JST PH connectors are too bulky.
This cable uses 1:1 symmetric wiring, meaning pin 1 on one connector maps directly to pin 1 on the other, pin 2 to pin 2, and so on through all six pins. Molex PicoBlade compatible.
Key Features
- 1.25 mm Pitch Connectors – Ultra-slim profile for space-constrained builds
- 1:1 Symmetric Wiring – Straight-through pin mapping from end to end
- Friction-Lock Mechanism – Secure, click-in connection that won't pull loose
- 20 cm Length – Convenient short-run cable for internal wiring
- 6 Pins – Suitable for multi-signal connections including I2C, SPI, or UART with extras
Ideal For
- Connecting breakout boards and sensors with 1.25 mm pitch headers
- Internal wiring in compact enclosures and portable projects
- Replacing bulkier JST PH or 0.1" dupont connections
Package Contents
- 1× 1.25 mm pitch 6-pin cable (20 cm, 1:1 wiring)
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
- Headers
- Rows of connector contacts on a fixed pitch (commonly 2.54 mm) used to link a board to a breadboard, jumper wires, or another board. They come as male pin headers and female socket headers; when a module ships with pre-soldered headers it can be used straight away, whereas bare pads require soldering 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.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
- UART
- UART is a simple asynchronous serial interface that sends data over separate transmit and receive wires, usually labelled TX and RX, with both ends set to the same baud rate. It is a common way for microcontrollers and other serial devices to exchange data.
