STMicroelectronics STEVAL-IDB011V2

Overview

STEVAL-IDB011V2 from STMicroelectronics is a Bluetooth® Low Energy 5.2 evaluation platform built around the BlueNRG-LP SoC (QFN48), integrating MEMS accelerometer/gyroscope (LSM6DS3), pressure/temperature sensor (LPS22HB), digital microphone (MP34DT05-A), Arduino R3 headers, SMA antenna connector, and embedded CMSIS-DAP debugger. It supports master/slave/simultaneous roles, +8 dBm output power, and -103 dBm sensitivity at 125 bps long range.

For engineers reviewing the STEVAL-IDB011V2 datasheet, STEVAL-IDB011V2 pinout, STEVAL-IDB011V2 application, or STEVAL-IDB011V2 equivalent, this board enables rapid prototyping of BLE sensor fusion applications with dual power options (USB/battery), drag-and-drop programming, and full peripheral access including 2×I²C, 2×SPI/I²S, UART, PDM, and 12-bit ADC.

Technical Context

The platform centers on the BlueNRG-LP SoC - a 64 MHz Arm® Cortex®-M0+ MCU with 256 KB flash, 64 KB SRAM, MPU, and BLE 5.2 protocol stack support. It implements LE L2CAP connection-oriented channels, periodic advertising sync transfer, and LE power control with path loss monitoring.

Hardware co-integration includes three user LEDs, two push buttons, and sensor interfaces routed to dedicated I²C/SPI buses. Power management uses LDL212D33R LDO (3.3 V, 300 mA), while USB-to-serial conversion is handled by an integrated STM32F10x-based ST-LINK/V2-1 debug interface.

FAQ

Does STEVAL-IDB011V2 support over-the-air (OTA) firmware updates?

Yes - the board supports BLE OTA firmware updates using the STSW-BNRGLP-DK software package. The BlueNRG-LP SoC includes a secure bootloader and dual-bank flash architecture enabling robust, fail-safe OTA upgrades without external programmer.

What development software is required to use STEVAL-IDB011V2?

The official STSW-BNRGLP-DK development kit software is required, including BlueNRG-LP SDK, BLE stack libraries, example projects, and STM32CubeMX configuration tools. No third-party IDE license is needed - full support for Keil MDK, IAR EWARM, and GCC-based toolchains is provided.

Can the onboard sensors be used independently of the BLE radio?

Yes - all sensors (LSM6DS3, LPS22HB, MP34DT05-A) are connected via dedicated I²C and SPI buses with configurable pull-ups and interrupt routing. Their drivers are included in the SDK, allowing standalone data acquisition, sensor fusion, or custom processing without BLE stack initialization.

Is external antenna tuning required when using the SMA connector?

No - the RF front-end includes a matched 50 Ω path from BlueNRG-LP RF pins to the SMA connector, verified per DB4617 schematic. The board ships calibrated; only standard 50 Ω test equipment or antennas should be connected directly without impedance-matching adjustments.
