STMicroelectronics STEVAL-NBIOTV1

The STEVAL-NBIOTV1 is a compact, battery-powered evaluation platform and reference design tailored for asset tracking, smart city applications, and metering. Unlike typical reference designs that focus on a single component, the STEVAL-NBIOTV1 integrates multiple key elements: the ST87M01 ultracompact, low-power NB-IoT industrial module featuring additional ADC, GNSS, and Wi-Fi positioning capabilities; the STM32U585RI microcontroller; onboard sensors; and extra memory via a 32 Mbit serial SPI page EEPROM. This all-in-one integration enables rapid IoT application development without requiring external add-ons or additional hardware. An example application code is provided to optimize low-power operation and accelerate time-to-market. Connectivity and location-based services are powered by the ST87M01 narrowband IoT (NB-IoT) and GNSS module. Multiple communication interfaces are supported, including UART, I²C, and SPI. Efficient power management and data storage components are integrated, and an expansion connector allows easy addition of further functionalities. Please note, the board does not include an STM32 debugger/programmer; a compatible debugger can be purchased separately. The recommended part numbers are STLINK-V3MINIE or, alternatively, STLINK-V3SET.
