If you fancy connecting to anything else with a JST SH compatible 3-pin connector, this cable will do the trick.

For example, Adafruit's NeoPixel JST Breakout boards, or UPDI Friend, or Sparkle Motion, or other boards they 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. They're also compatible with the debug port on Pimoroni Pico boards, such as Pico LiPo 2 or Pico Plus 2. Note that the colors Adafruit got are somewhat matchy with their '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
