The Lyra P Development Kit features a Qwiic® connector compatible with Qwiic Connect System hardware. The Qwiic
connector provides an easy way to expand the functionality of the Lyra P Development Kit with sensors, LCDs, and other
peripherals over the I
2
C interface. The Qwiic connector is a 4-pin polarized JST connector, which ensures the cable is inserted
the right way.
Qwiic Connect System hardware is daisy chainable as long as each I
2
C device in the chain has a unique I
2
C address.
Note: The Qwiic I
2
C connections on the Lyra P Development Kit are shared with the mikroBUS I
2
C signals.
The Qwiic connector and its connections to Qwiic cables and the Lyra P are illustrated in the figure below.
