The Lyra 24S Development Kit has been designed to simplify IoT development with the Lyra 24S wireless module. The kit
includes a mikroBUS
™ socket and Qwiic® connector, allowing users to add features to the kit with a large selection of off-the-
shelf boards.
Programming the Lyra 24S Development Kit is easily done using a USB Micro-B cable and the on-board J-Link debugger. A
USB virtual COM port provides a serial connection to the target application, and the Packet Trace Interface (PTI) offers
invaluable debug information about transmitted and received packets in wireless links. The Lyra 24S Development Kit is
supported in
Silicon Labs’ Simplicity Studio™ and a Board Support Package (BSP) is provided to give application developers
a flying start.
Connecting external hardware to the Lyra 24S Development Kit can be done using the 20 breakout pads which present
peripherals from the Lyra 24S such as I2C, SPI, UART and GPIOs. The mikroBUS socket allows inserting mikroBUS add-on
boards which interface with the Lyra 24S through SPI, UART or I2C. The Qwiic connector can be used to connect hardware
from the Qwiic Connect System through I2C.
