The STMicroelectronics B-L462E-
The kit features an ultra-small size all-in-one cellular module from Murata, which embeds ST’s ultra-low-power STM32L462* microcontroller, ST4SIM-200M GSMA-certified embedded SIM (eSIM), and an LTE-M/NB-IOT chipset. The eSIM is pre-programmed with a bootstrap connectivity profile from Truphone, an ST Authorized Partner. The kit leverages out-of-the-box data connectivity and enables remote SIM provisioning and SIM Over-The-Air updates. The user can immediately start the board by connecting to a power supply using a USB cable or inserting three AAA batteries in the connector provided before activating the eSIM to let the board connect to a cellular network to begin developing the application.
The B-L462E-CELL1 kit is designed to strongly resist cellular connectivity attacks thanks to the ST4SIM-200M eSIM solution based on the proven ST33 Arm® SecurCore® SC300™ secure element, which is CC EAL5+ and GSMA SGP.02 v3.2 certified. The ST4SIM is ready to host a Root-of-Trust applet for enhanced protection against cyber-attacks.

With ST’s ultra-low-power technologies in the STM32L4, which draws about 2µA in STOP 2 mode, and acellular chipset drawing less than 1.4µA in Power Saving Mode (PSM), the B-L462E-CELL1 Discovery kit provides 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 ST4SIM-200M is manufactured and personalized at ST’s GSMA-accredited sites and, with the programmed eSIM profile, eases connection to networks** in more than 160 countries.
“Cellular connectivity will take a significant share on the IoT market and is why ST has teamed with Murata on a module powered by STM32L4 and embedded ST4SIM eSIM,” said Hakim Jaafar, Head of Wireless MCU Marketing, STMicroelectronics. “For the best out-of-the-box experience, ST has also worked closely with Truphone on a free-of-charge LTE-M connectivity data plan to allow IoT Cellular Discovery kit users to quickly develop and prototype their solutions.”
“This announcement underscores the importance of our collaboration with STMicroelectronics. By doing so, we developed a solution that addresses two of the major pain points cellular IoT device developers face – software development and cellular certification. This module also delivers class-leading optimization and flexibility in a highly integrated package to enable global connectivity,” added Yong Fang, Cellular IoT Product Manager, Murata Americas.
The B-L462E-CELL1 Discovery kit is available now. Budgetary pricing starts at $74.00.
