The RM126x Development Kit is an ultra-low cost, small form factor development and evaluation platform for the RM126x
Wireless LoRaWAN Module.
The RM126x Development Kit is focused on rapid prototyping and concept creation of IoT applications. It is designed around
the RM126x Module, based on the EFR32BG22 System-on-Chip and SX126x LoRa chipset, 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.
