The Lyra P Development Kit is an ultra-low cost, small form factor development and evaluation platform for the Lyra P
Wireless Bluetooth® Module.
The Lyra P Development Kit is focused on rapid prototyping and concept creation of IoT applications. It is designed around the
Lyra P Module, based on the EFR32BG22 System-on-Chip, which is an ideal device family for developing energy-friendly
connected IoT applications.
The kit features a USB interface, an on-board SEGGER J-Link debugger, one user-LED and button, and support for hardware
add-on boards via a mikroBus socket and a Qwiic connector. The hardware add-on support allows developers to create and
prototype applications using a virtually endless combination of off-the-shelf boards from mikroE, sparkfun, AdaFruit, and
Seeed Studios.
