The RM126x Development Kit has been designed to simplify IoT development with the RM126x 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 RM126x 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.
The RM126x Development board Kit DVK-RM126x ships with signed RM126x Bootloader and AT application firmware
(customer using AT commands run from a host). Alternatively, the RM126x is supported in
Silicon Labs’ Simplicity Studio™
and an initial Board Support Package (BSP) is provided by Silicon labs to give application developers a flying start. Laird
Connectivity provides extensive sample applications RM126x for those customers developing with C code developing with the
Silicon Labs SDK, including the mandatory RM126x radio regulatory protection layer.
Connecting external hardware to the RM126x Development Kit can be done using the 20 breakout pads which present
peripherals from the RM126x such as I2C, SPI, UART and GPIOs. The mikroBUS socket allows inserting mikroBUS add-on
boards which interface with the RM126x through SPI, UART or I2C. The Qwiic connector can be used to connect hardware
from the Qwiic Connect System through I2C.
