NEW PRODUCTS – JST PH 4-Pin I2C STEMMA 200mm Cables – Female + Male


This cable will let you turn a JST PH 4-pin cable port into 3 individual wires with high-quality 0.1″ female sockets on the end. We’re carrying these to match up with any of our boards with ‘STEMMA’ connectors on them such as the Hallowing or Trellis M4. Can also be used with any STEMMA breakouts! This one has socket pins, so it could be used to connet to wires or headers.

The wires are even color coded:

  • Black for GND
  • Red for V+
  • White for SDA
  • Green for SCL

Even though this is a JST PH connector, it will fit into a Seeed Grove connector and have the right matching wires as well.
