ST B-L4S5I-IOT01A

The B-L4S5I-IOT01A IoT node development kit enables users to develop applications with direct cloud server connectivity. The kit supports diverse application scenarios through low-power communication, multi-channel sensing, and the STM32L4+ series features based on the Arm® Cortex®-M4 core. Compatible with ARDUINO® Uno V3 and Pmod™ interfaces, it offers unlimited expansion with a wide range of dedicated add-on boards.
