SPIDER Automation B-L4S5I-IOT01A IoT Discovery Kit | STM32L4S5VIT6 Evaluation Board
Description
SPIDER Automation STMicroelectronics B-L4S5I-IOT01A IoT Discovery Kit enables developers and engineers to build advanced, multi-channel cloud-connected IoT applications with direct server integration. At its heart lies the ultra-low-power STM32L4S5VIT6 microcontroller, leveraging an ARM Cortex-M4 core with a hardware floating-point unit (FPU), 2 Mbytes of Flash memory, and 640 Kbytes of RAM packed into an LQFP100 housing.
This all-in-one discovery kit is engineered to support a wide diversity of smart applications by combining ultra-low-power wireless communications, multiway environmental sensing, and hardware-level security. Featuring onboard Wi-Fi, Bluetooth LE, dynamic NFC, digital microphones, motion sensors, a time-of-flight distance detector, and an STSAFE secure element, it delivers an exceptional out-of-the-box prototyping ecosystem. Complete with Arduino Uno V3 and Pmod expansion headers and an embedded ST-LINK/V2-1 debugger, it is fully supported by comprehensive software libraries and the STM32Cube ecosystem.
