If you fancy connecting to anything else with a JST SH compatible 3-pin connector, this cable will do the trick. For example, our NeoPixel JST Breakout boards, or UPDI Friend, or Sparkle Motion, or other boards we have with JST SH connectors on them for simple digital/analog IO. It has a 1mm pitch JST SH connector on both ends - perfect for 'chaining' boards together.
You can also use these on the debug port on a Pico WH, or the two ports on a Pico Debug Probe. Note that the colors we got are somewhat matchy with our '2mm PH' sized  STEMMA cables, so if you are using them for the Debug Probe port, the colors will be as follows:
  1. White - SWCLK or UART TX
  2. Red - Ground (yeah, we know this isn't ideal)
  3. Black - SWDIO or UART RX
For more information, visit the JST website for JST PH and JST SH connectors and cables.

Jargon buster

Plain-language definitions for the technical terms used above.

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.
RX
RX means receive, usually showing data being received by the board. An RX indicator LED can help with troubleshooting USB or serial communication.
TX
TX means transmit, usually showing data being sent from the board. A TX indicator LED can help you see when the board is communicating or uploading code.
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.
