The B-L462E-CELL1 Discovery kit is a turnkey development platform for cellular IoT devices. The Discovery kit contains a low-power Discovery main board powered by an LBAD0ZZ1SE module, a global coverage antenna, and a fan-out board. The LBAD0ZZ1SE module includes an STM32L462REY6TR microcontroller, an LBAD0XX1SC-DM ultra-small LTE Cat M/NB modem, and an ST4SIM-200M GSMA-certified embedded SIM with a prepaid cellular connectivity data plane. ST4SIM-200M can also be used as an embedded secure element (eSE) for application.STMod+ and extended pins connectivity provide unlimited expansion capabilities with a large choice of specialized add-on boards. Moreover, the fan-out board supports add-on boards using mikroBUS™, ESP‑01, Grove I2C, Grove UART, and breadboard. The B-L462E-CELL1 Discovery kit includes an ST-LINK debugger/ programmer and comes with the comprehensive STM32Cube software libraries together with packaged software examples to demonstrate end-to-end connectivity.
