Original Design
This product was designed by 8086 Consultancy. By buying this product you support original hardware creators.

The QT/Qw QUAD is a small board with four 4-pin JST SH compatible connectors designed to be used with STEMMA QT or Qwiic I2C devices/controllers.

The extender allows you to keep the plug and play feature of STEMMA QT/Qwiic when using multiple boards which only have a single connector and don't allow devices to be chained.

When using the extender please remember to check for I2C conflicts as the devices are still connected to the same I2C bus.
