STM32 B-L462E-CELL1 Cellular IoT Development Kit for Developing Smart Connected Devices

STM32 B-L462E-CELL1 Cellular IoT Development Kit

STMicroelectronics has introduced the B-L462E-CELL1 Discovery kit that combines critical hardware and software building blocks, including GSMA-certified embedded SIM (eSIM) to quickly develop power-conscious Cellular IoT devices that connect to the Internet through LTE-Cat M and NB-IoT networks. The kit features an ultra-small size all-in-one cellular module that includes ST’s ultra-low-power STM32L462 microcontroller, ST4SIM-200M GSMA-certified embedded SIM (eSIM), and an LTE-M/NB-IoT chipset.


Preprogrammed with the bootstrap connectivity profile, the kit leverages out-of-the-box data connectivity and enables remote SIM provisioning and SIM Over-The-Air updates. The kit uses the ST4SIM-200M eSIM solution based on the proven ST33 Arm SecurCore SC300 for strong resistivity against connectivity attacks. The onboard sensors such as LSM303AGR accelerometer-magnetometer, HTS221 relative humidity, and temperature sensor, and LPS22HH pressure sensors simplify the development of motion and environmental solutions. The device also includes a 0.96-inch OLED display, indicator LEDs, and a USB connection.


The B-L462E-CELL1 Discovery kit has been designed with ultra-low-power technologies in the STM32L4, which draws about 2µA in STOP 2 mode, and cellular chipset drawing less than 1.4µA in Power Saving Mode (PSM). The device acts as a platform to develop equipment with a battery life of up to 10-years for smart-city, smart-industry, smart-agriculture, smart-metering, and wearable applications. The B-L462E-CELL1 Discovery kit is available now. Budgetary pricing starts at $74.00.
