Cellular IoT Discovery Kit from STMicroelectronics Contains eSIM with Bootstrap Profile for Immediate Connection – EEJournal


Geneva, April eight, 2021 – The STMicroelectronics B-L462E-CELL1 Discovery Package brings collectively key hardware and software program constructing blocks, together with GSMA-certified Embedded SIM (eSIM), to rapidly develop high-performance mobile IoT units that may function on the Connect with the Web LTE Cat M and NB IoT networks. It really works properly for embedded builders and IoT evangelists, and is inexpensive for OEM and mass market clients.

The package comprises an ultra-small all-in-one mobile module from Murata[1]The STM32L462 * microcontroller with extraordinarily low energy consumption from ST, the GSMA-certified embedded SIM card (eSIM) ST4SIM-200M and an LTE-M / NB-IOT chipset are built-in right here. The eSIM is preprogrammed with a bootstrap connectivity profile from Truphone, an ST approved associate. The package leverages out-of-the-box knowledge connectivity and allows distant SIM provisioning and SIM over-the-air updates. The consumer can instantly begin the cardboard by connecting a USB cable to an influence adapter or by inserting three AAA batteries into the connector offered earlier than activating the eSIM in order that the cardboard can connect with a mobile community to start out creating the appliance.

The B-L462E-CELL1 package is designed on this approach due to the e4 resolution ST4SIM-200M eSIM, which relies on the confirmed safe aspect ST33 Arm® SecurCore® SC300 ™ and is CC EAL5 + and GSMA SGP.02 v3.2 licensed that it’s extremely immune to assaults on mobile connections. The ST4SIM is able to host a Root of Belief applet for improved safety towards cyber assaults.

A spread of on-board sensors simplify the event of movement and environmental monitoring options. They embrace ST’s LSM303AGR accelerometer magnetometer, HTS221 relative humidity and temperature sensor, and LPS22HH stress sensor. There’s additionally a zero.96-inch OLED show, indicator LEDs, and a USB port.

The STM32Dice software program growth package deal X-CUBE-CELLULAR controls the Discovery Package and helps the Berkeley (BSD) Sockets Software Programming Interface (API). With BSD’s standardized perform requires Web communication, customers can join their prototypes to the Web with out having to develop an AT command driver to manage the modem. X-CUBE-CELLULAR features a demonstration software and mobile framework in supply code and may be simply imported and configured utilizing the highly effective, free STM32Dice software program toolset.

With ST’s ultra-low energy applied sciences within the STM32L4, which eat round 2 µA in STOP 2 mode, and a mobile chipset that consumes lower than 1.four µA in energy-saving mode (PSM), the B-L462E CELL1 Discovery-Package a platform for the event of units with a battery lifetime of as much as 10 years for good metropolis, good business, good agriculture, good metering and wearable purposes. The ST4SIM-200M is manufactured and personalised on the GSMA-accredited ST places and facilitates the connection to networks ** in additional than 160 international locations with the programmed eSIM profile.

“Mobile connectivity could have a big share of the IoT market. That is why ST has teamed up with Murata on a module primarily based on STM32L4 and embedded ST4SIM eSIM,” stated Hakim Jaafar, Head of Wi-fi MCU Advertising and marketing at STMicroelectronics. “For the very best out-of-the-box expertise, ST has additionally labored intently with Truphone on a free LTE-M connectivity knowledge plan in order that customers of the IoT Mobile Discovery Package can rapidly develop and prototype their options.”

“This announcement underscores the significance of our collaboration with STMicroelectronics. On this approach, we’ve created an answer that addresses two of the principle issues confronted by mobile IoT gadget builders – software program improvement and mobile certification. This module additionally affords world-class optimization and suppleness in a extremely built-in package deal to allow world connectivity, ”added Yong Fang, product supervisor for mobile IoT at Murata Americas.

The B-L462E-CELL1 Discovery Package is offered now. Price range costs begin at $ 74.00.
