STMicroelectronics’ New Cellular IoT Discovery Kit

STMicroelectronics has launched a cellular IoT Discovery kit containing eSIM with boot strap profile.

 

STThe STMicroelectronics B-L462E-CELL1 Discovery kit brings together the 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.

 

“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.”

 

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.

 

The STM32Cube software expansion package, X-CUBE-CELLULAR drives the Discovery kit and supports the Berkeley (BSD) sockets application programming interface (API).

 

BSD’s standardized function calls for Internet communication lets users connect their prototypes to the Internet without needing to develop an AT-command driver to control the modem.

 

With ST’s ultra-low-power technologies in the STM32L4, which draws about 2µA in STOP 2 mode, and a cellular 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.
