3.6.2 Qwiic Connector
The xG24 Dev Kit features a Qwiic connector compatible with Qwiic Connect System hardware. The Qwiic connector provides an easy
way to expand the functionality of the xG24 Dev Kit with sensors, LCDs, and other peripherals over the I
2
C interface. The Qwiic con-
nector is a 4-pin polarized JST connector, which ensures the cable is inserted the right way.
Qwiic Connect System hardware is daisy chain-able as long as each I
2
C device in the chain has a unique I
2
C address.
Note:
The Qwiic I
2
C lines are shared with the on-board I
2
C sensors, and are also exposed on the breakout pads.
The table below gives an overview of the Qwiic connections to the EFR32MG24.

3.6.3 Mini Simplicity Connector
The Mini Simplicity connector is a 10-pin 1.27 mm pitch connector that allows the use of an external debugger such as the one found
on one of the Silicon Labs Wireless mainboards. See section
for more details. The pinout of the connector on
the board is described in the table below with the names being referenced from the EFR32MG24.
